Answer:

m∠I = 50 degrees

Step-by-step explanation:

Mathematically, the base angles of an isosceles triangle are equal

So in this case, since H is a vertex;

m∠I + m∠H + m∠G = 180

m∠I = m∠G = x

2x + 80 = 180

2x = 180-80

2x = 100

x = 100/2

x = 50

Step-by-step explanation:

The ratios 28:15 and 3:13 are in their simplest form, meaning that they cannot be simplified any further.

Meanwhile, the other 3 ratios are not in their simplest form and can still be simplified if they are divided by either 2 or 4.

Answer:

im pretty sure it is answer A. 4.802 x 10^7

Step-by-Step explanation

The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.

Calculating scientific notation for a positive integer is simple, as it always follows this notation:

a x 10b

Follow the steps below to see how 48,020,000 is written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 48,020,000

New Number: 4.8020000

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 4 . 8 0 2 0 0 0 0

Decimal Count:   1 2 3 4 5 6 7

There are 7 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 4.802 (Please notice any zeroes on the end have been removed)

b = 7

Now the whole thing:

4.802 x 107

Step 4

Check your work:

107 = 10,000,000 x 4.802 = 48,020,000

Answer:

x = 55

Step-by-step explanation:

to find angle BPR you would do:

180 - 120 = 60

so BPR is 60°

now to find x you do this:

65 + 60 + x = 180

125 + x = 180

x = 55

Answer:

Step-by-step explanation:

sin x =3/4

x is an obtuse angle and sin x is positive .

∴ x lies in 2nd quadrant.

Hence cos x is negative.

[tex]cos x=-\sqrt{1-sin^2x} =-\sqrt{1-(3/4)^2} =-\sqrt{1-\frac{9}{16} } =-\sqrt{\frac{7}{16} } =-\frac{\sqrt{7} }{4}[/tex]

Solving a trigonometric equation, it is found that:

[tex]\cos{x} = -\frac{\sqrt{7}}{4}[/tex]

The sine and the cosine of an angle x are related by the following equation:

[tex]\sin^2{x} + \cos^2{x} = 1[/tex]

In this problem:

[tex]\sin{x} = \frac{3}{4}[/tex], thus:

[tex]\sin^2{x} + \cos^2{x} = 1[/tex]

[tex](\frac{3}{4})^2 + \cos^2{x} = 1[/tex]

[tex]\frac{9}{16} + \cos^2{x} = 1[/tex]

[tex]\cos^2{x} = 1 - \frac{9}{16}[/tex]

[tex]\cos^2{x} = \frac{7}{16}[/tex]

[tex]\cos{x} = \pm \sqrt{\frac{7}{16}}[/tex]

Since the cosine is negative.

[tex]\cos{x} = -\frac{\sqrt{7}}{4}[/tex]

Lets define a=1st number, b=2nd number, and c=3rd number

We know that a+b+c=126

We also know that the second number is 6 more than the first, so we can represent this as b=a+6

We also know that the third number is 3 times the first which can be represented as c=3a

We can plug these new values into our original equation and get:

a+(a+6)+(3a)=126

2a+6+3a=126 COMBINE LIKE TERMS

5a+6=126

5a=120

a=24

Our first number is 24.

Our second number is 6 more than our first number, so the second number is 24+6=30

Our third number is 3 times the first number, so the third number is 3(24)=72

We can check by plugging these numbers in for a, b, and c in our original equation

a+b+c=126

24+30=72=126

126=126

The numbers are 26, 20, and 80.

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,

Three numbers:

First = a

Second = b

Third = c

Now,

a + b + c = 126 ____(1)

c = 4b ____(2)

b = a - 6 _____(3)

From (1), (2), and (3) we get,

a + (a - 6) + 4b = 126

a + a - 6 + 4b = 126

2a + 4b = 126 + 6

2a + 4b = 132

2a + 4(a - 6) = 132

2a + 4a - 24 = 132

6a = 132 + 24

6a = 156

a = 26

Now,

a = 26

b = a - 6 = 20

c = 4b = 4 x 20 = 80

Thus,

The numbers are 26, 20, and 80.
