1.)

sin(21) = x/26    <----------- multiply by 26 to get x by itself

26*sin(21) = x  <----------- multiply 26 by sin(21)

9.32 = x      <------ rounded answer

2.)

cos(64) = x/11      <------------ multiply by 11 to get x by itself

11*cos(64) = x      <---------------- multiply 11 by cos(64)

x= 34    y= 99    z= 41

Step-by-step explanation: A.

Answer:

D

Step-by-step explanation:

First I solved for the triangle on the right by adding 58 and 81 then subtracting by 180 and I got 41 degrees for the missing angle. Now for the left triangle you subtract 47 from 180 and you get 133. Answer choice D is the only answer choice that has x and y equal to 133 this is why answer choice D is the correct solution.

Answer:

x=5

EF = 22in.

Step-by-step explanation:

We know EF and DE are equal, so we can solve for x.

5x-3=3x+7

5x-3x=7+3

2x=10

x=5

Now we plug that into EF.

EF = 3x+7 = 3(5)+7 = 15+7=22

Equations with one solution: [tex]-2(x-3) = 2x-6[/tex]

Equations with no solution:

[tex]6(x+5) = 6x+11\\5(x-2) = 5x-7[/tex]

Equations with infinite many solutions: [tex]-3(x-4) = -3x+12[/tex]

Step-by-step explanation:

We will solve each equation to see if it has one solution, no solution or infinite many solutions.

An equation where the value of variable can be found has one solution.

An equation with no solution has both sides different.

An equation with infinite solution will have both sides equal after solution(number)

So,

Equation 1:

5(x-2) = 5x-7

[tex]5(x-2) = 5x-7\\5x-10 = 5x-7\\5x-5x = -7+10\\0 = 3[/tex]

As both sides are not equal, equation has no solution.

Equation 2:

[tex]-3(x-4) = -3x+12\\-3x+12 = -3x+12\\-3x+3x = -12+12\\0=0\\[/tex]

As both sides are equal the equation has infinite many solutions.

Equation 3:

[tex]-2(x-3) = 2x-6\\-2x+6 = 2x-6\\-2x-2x = -6-6\\-4x = -12\\\frac{-4x}{-4} = \frac{-12}{-4}\\x = 3[/tex]

As x=3, the equation has only one solution.

Equation 4:

[tex]6(x+5) = 6x+11\\6x+30 = 6x+11\\6x-6x+30 = 11\\30 =11[/tex]

The equation has no solution.

Hence,

Equations with one solution: [tex]-2(x-3) = 2x-6[/tex]

Equations with no solution:

[tex]6(x+5) = 6x+11\\5(x-2) = 5x-7[/tex]

Equations with infinite many solutions: [tex]-3(x-4) = -3x+12[/tex]

Answer:

Step-by-step explanation:

I took it on edg 2020

The Complex Alternative form to the expression (5[cos(π/4) + i sin(π/4)])^3 is given as: (Option C).

A complex number of equations will take the form x + yi, where x and y are real numbers and i is an indeterminate that satisfies the rule i² = -1.

Hence, the solution to the above is given as follows:

Step 1 - Ludooph's number pi is given as:

π ≈ 3.14159265

Step 2 - Divide  3.14159265/4

= 0.78539816

Step 3

Cos (0.78539816)

= 0.70710678

It is assumed that the trigonometric angle argument is in radians.

Step 4

Divide: 3.14159265 / 4

= 0.78539816

Step 5 - find the Sin of the result of step 4

sin(0.78539816)

= 0.70710678

It is assumed that the trigonometric angle argument is in radians.

Step 6

Multiply i by the result of Step No 5

=  i * 0.70710678

= 0.7071068i

Step 7 - Add the result of step no. 3 and the result of step number 6

= 0.70710678 + 0.7071068i

= 0.7071068+0.7071068i

Step 8 Multiply 5 by the result of step 7

= 5 * (0.7071068+0.7071068i)

= 5 * 0.70710678118655 + 5 * 0.70710678118655i

= 3.53553391+3.53553391i

= 3.53553391 +i(3.53553391)

= 3.5355339+3.5355339i

Step 9 - Exponentiate the results of Step 8 to the third power:

= (3.5355339+3.5355339i) ^ 3

= (5 × ei π/4)3 = 53 × ei 3 × π/4

= 125 × ei 3π/4

= -88.3883476+88.3883476i

If left in the Alternate Complex form, we have:
125[cos(3π/4) + i sin(3π/4)]

Answer:

The description of the set is [tex]A = \{s\in \mathbb{C}|\|s\| = 2\}[/tex].

Step-by-step explanation:

From Complex Analysis, we remember that complex numbers are numbers whose form is:

[tex]s = a+i\, b[/tex], [tex]a,b \in \mathbb{R}[/tex] (1)

Where [tex]i = \sqrt{-1}[/tex].

In addition, the distance from the origin is defined by the following Pythagorean identity:

[tex]\|s\| = \sqrt{a^{2}+b^{2}}[/tex] (2)

The following condition must be satisfied:

[tex]\|s\| = 2[/tex]

Then, the set of all complex numbers that are at a distance of 2 units from the origin is described below:

[tex]A = \{s\in \mathbb{C}|\|s\| = 2\}[/tex] (3)

The set of all complex numbers that are at a distance of 2 units from the origin is [tex]\{z\in \mathbb{C} :\text{ }|z|=2\}[/tex]

A complex number, written in rectangular form is

[tex]z=a+ib\\a,b\in \mathbb{R}[/tex]

The distance of a complex number from the origin (the modulus of the complex number, denoted by [tex]|z|[/tex]) is given by the formula

[tex]|z|=\sqrt{a^2+b^2}[/tex]

Since we want all the complex numbers to be at the distance of 2 units from the origin, they must satisfy

[tex]|z|=2[/tex]

thus, the set we are looking for is

[tex]D=\{z\in \mathbb{C} :\text{ }|z|=2\}[/tex]

where [tex]\mathbb{C}[/tex] is the set of all complex numbers

Answer:

ITS B !!!!!!!!!!!!!

Step-by-step explanation:

The equivalent expression is -9/4 ÷ (-2/3).

Option B is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Negative 2 and one-fourth divided by negative two-thirds.

This can be written as,

-2(1/4) ÷ (-2/3)

= -9/4 ÷ (-2/3)

= -9/4 x -3/2

= 27/8 _____(A)

Now,

StartFraction 9 over 4 EndFraction divided by three-halves

This can be written as,

9/4 ÷ 3(1/2)

= 9/4 x 2/7

= 18/28 ______(1)

Negative StartFraction 9 over 4 EndFraction divided by (negative two-thirds)

This can be written as,

-9/4 ÷ (-2/3)

= -9/4 x -3/2

= 27/8 ______(2)

Negative StartFraction 9 over 4 EndFraction divided by two-thirds

This can be written as,

-9/4 ÷ 2/3

= -9/4 x 3/2

= -27/8

StartFraction 9 over 4 EndFraction divided by (negative three-halves)

This can be written as,

9/4 ÷ -3(1/2)

= 9/4 x 2/7

= 18/28

Thus,

From (A) and (2),

-9/4 ÷ (-2/3) is the equivalent expression.

Answer:

46 degrees

Step-by-step explanation:

Answer:

30% profit

Step-by-step explanation:

The amount by which the shopkeeper reduced the advertised selling price = 20%

The resulting profit over the cost price = 4%

Let x represent the initial advertised selling price, and let y represent the new selling price, and let c represent the cost price, we have;

x - 20% of x = y

x - x × 20/100 = y

0.8·x = y

y = c + 4% of c = 1.04·c

∴ 0.8·x = 1.04·c

x = 1.04·c/0.8 = 1.3·c

x = 1.3·c = c + 0.3·c = c + 30% of c

x = c + 30% of c

From which we have that the initial advertised selling price, x = The cost price + 30% of the  cost price

Therefore, the initial advertised selling price = The cost price + 30%profit on   cost price.

The shopkeeper would have made 30% profit if the dress had then been sold at the original selling price.

Answer:

A triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute. Therefore, an obtuse-angled triangle can never have a right angle; and vice versa. The side opposite the obtuse angle in the triangle is the longest.
