<h3>Supplementary Angles:</h3>

Angles which adds up to 180°.

<h3>Given:</h3>

A = 2x + 8

B = 2x + 8

<h3>To Find:</h3>

The measurement of B.

<h3>Solution:</h3>

A + B = 180°

or, 2x + 8 + 2x + 8 = 180°

or, 4x + 16 = 180°

or, 4x = 180 - 16 = 164°

or, x = 164/4 = 41°

<h2>Answer:</h2>

B = 2x + 8 = 2(41) + 8 = 82 + 8 = 90°

<u>B</u><u> </u><u>=</u><u> </u><u>9</u><u>0</u><u>°</u>

Answer:

The measurement of angle B is 90°

Step-by-step explanation:

Solve for x.

Since angle A and angle B are supplementary, they both add up to 180°.

So,

(2x + 8) + (2x + 8) = 180°

2x + 8 + 2x + 8 = 180°

4x + 16 = 180°

4x = 180° - 16

4x = 164°

x = 164 ÷ 4

x = 41

Now substitute the x value to angle B.

∠B = 2x + 8

∠B = 2(41) + 8

∠B = 82 + 8

∠B = 90°

Step-by-step explanation:

Reflection across the x-axis:

(x,y) -> (x,-y)

In other words, you want to <u>change the sign of the y</u>.

(3,-2) -> (3,2)

In 1994, the General Social Survey had a question that asked its participants (that currently smoked) if they had ever tried to
Roman55 [17]

Answer:

0.8239 is the population proportion of participants that tried quitting smoking.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 142

Participants that tried quitting smoking = 117

Parameter:

  • A parameter is a numerical value that describes a population.

Population proportion can be calculated as:

p = \dfrac{x}{n} \\\\p= \dfrac{117}{142} \\\\p= 0.8239

0.8239 is the population proportion of participants that tried quitting smoking.

20 points<br> What is the value of p in the linear equation ?<br><br> −4<br> −2<br> 2<br> 4
Nikolay [14]

Answer:

p=-2

Step-by-step explanation:

24p+12-18p=10+2p-6  

Subtract what is to the right of the equal sign from both sides of the equation.

24p+12-18p-(10+2p-6)=0

Then pull out the like terms(factors)

Which is: 4p+8

=4(p+2)

Put that to 0 and 4=0 which is not a solution because it's a non-zero constant.

So now put  p+2=0, subtract by 2 on both sides and the 2 cancels out and on the right side you have -2

p=-2
