Represent -5 / 4 and 5 / 4 on number line

71 and the blank angle are a linear pair/supplementary angles, meaning that their sum is 180 degrees.

71 + y = 180

y = 109

The sum of the interior angles of a triangle is 180 degrees. Therefore, all of the angles inside of the triangle will add up to 180.

109 + 46 + x = 180

x = 25

Answer: x = 25 degrees

Answer:

200 dollars

Step-by-step explanation:

Let's say p equals the cost price of the article. Since the man made 25% profit, that means he got 100% of what he originally paid plus another 25% of what he originally paid. In other words, he sold the article for 125% of the original price. Converting that to a decimal we get:

250=p*1.25

Some simple division gets us a cost price of 200 dollars.

x = 68

Explanation:

⇒ log₈(x - 4) = 2

apply log rules: logₐN = x then N = aˣ

⇒ (x - 4) = 8²

simplify

⇒ x - 4 = 64

add 4 on both sides

⇒ x = 64 + 4

add the integers

⇒ x = 68

Answer:

x = 68

Step-by-step explanation:

Given equation:

[tex] \rm log_{8}(x - 4) = 2[/tex]

To Find:

Value of x

Solution:

Rewrite the equation in exponential form which is equivalent to b^y = x.

[tex] \implies {8}^{2} = x - 4[/tex]

Now find the value of x.

[tex] \implies \:64 = x - 4[/tex]

Transpose 4 from RHS to LHS, make sure to change its sign from (-) to (+) .

[tex] \implies \: 64 + 4 = x[/tex]

Overturn the equation

[tex] \implies \: x = 68[/tex]

Thus, value of x is 68.

19

The value of function at x = 3 is,

⇒ f (3) = 19

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

The function is,

⇒ f (x) = 2x² + 1

Now, Substitute x = 3 in above function,

⇒ f (x) = 2x² + 1

[tex]x = 49degrees[/tex]

Step-by-step explanation:

[tex]131 + x = 180( \: < \: on \: str \: line = 180) \\ x = 180 - 131 \\ x = 49[/tex]

The required value of x for the given figure is 49°.

A straight line can be defined as a locus of points satisfying the equation ax + by + c = 0 for two coordinates x and y.

The sum of the angles on a straight line is always 180°.

In the given figure the angles 131° and x° are on the same straight line.

Since, the sum of the angles on a straight line is 180°.

The following equation can be written for the given figure,

x + 131 = 180

=> x = 180 - 131

       = 49

Hence, the value of x for the given figure is 49°.

The resultant speed of the plane is 100 mi/hr along the northeast direction.

Speed can be calculated as the ratio of distance traveled to the time taken

First, we need to find our coordinate axis, we will define the x-axis as the east and the y-axis as the north.

We are given that the plane travels at 150 mi/hr at 100° east of north, notice that if we measure from the positive x-axis, this is equivalent to an angle of -10°.

Then the x-component of the velocity ;

150mi/hr x cos(-10°) = 147.7 mi/hr

The y-component of the velocity;

150mi/hr x sin(-10°) = -26 mi/hr.

So, the vector is:

V = 147.7 mi/hr, -26 mi/hr

Now we know that the wind blowing at 50mi/hr at southwest, exactly southwest would be at an angle of 225°,

Thus, the components of the vector are:

x-component: 50mi/hr x cos(225°) = -35.4 mi/hr

y-component: 50mi/hr x sin(225°) = -35.4 mi/hr.

So, the vector is:

W = < -35.4 mi/hr, -35.4 mi/hr>

The sum of the vectors gives the total velocity of the plane in the wind is;

V + W = < 147.7 mi/hr -35.4 mi/hr , -26 mi/hr -35.4 mi/hr >

V + W = <112.3 mi/hr, -61.4 mi/hr>

The direction of a vector is;

θ = Atan(y/x)

Then, in this case the direction of the plane is:

θ = Atan(-61.4 mi/hr/112.3 mi/hr) = -28.7°

1. Height of the equilateral triangle is: √3 units

2. Area of the equilateral triangle = √3 units²

3. Area = √3/4 x², when each side is x.

A triangle that has all its three sides equal in length, is referred to as an equilateral triangle.

1. Given the each side measures 2 units, and h is the height, applying the Pythagorean theorem, we would have:

h = √(2² - 1²)

h = √(4 - 1)

h = √3

2. Area of the equilateral triangle = 1/2bh = 1/2(2)(√3)

Area of the equilateral triangle = √3 units²

3. If x is the side length of the equilateral triangle, we would have:

height (h) = √[x² - (x/2)²] = √[x² - x²/4] = √(3x²/4) = √3/2x

Area = 1/2bh = 1/2(x)(√3/2x) = √3/4 x²
