Answer:

A. (4n + 22) + (8n - 10) = 180

B. n = 14

C. 78° and 102°

Step-by-step explanation:

A. The relationship between the two angles that are a linear pair is: their sum gives us 180°. That is:

(4n + 22) + (8n - 10) = 180

B. (4n + 22) + (8n - 10) = 180

Solve for n.

4n + 22 + 8n - 10 = 180

Collect like terms

12n + 12 = 180

Subtract 12 from both sides

12n + 12 - 12 = 180 - 12

12n = 168

Divide both sides by 12

\frac{12n}{12} = \frac{168}{12}

n = 14

C. Plug in the value of 14 to get the measurement of both angles

(4n + 22) = 4(14) + 22 = 56 + 22 = 78

(8n - 10) = 8(14) - 10 = 112 - 10 = 102

Find the measure of the smaller angle in the figure
Nataliya [291]
You know that the two angles make up a perfectly flat line, which is a 180<span>° angle. So we can create the equation:'

3x + 10 = 12x

Now solve for 'x'. Subtract 3x to both sides:

10 = 9x

Divide 9 to both sides:

x = 10/9

We want to find the smaller angle, so put this value in for 'x' in '3x + 10':

3x + 10

3(10/9) + 10

30/9 + 10

13 1/3</span><span>°</span>

Can someone SMART actually help me
lisov135 [29]
The answer is 196/3 pi in^3. All you have to do is multiply 7x7, then you have to multiply that by 1/3 and 4, and you get 65.333333333. Then, you have to turn it into a fraction. You have to multiply 65 by 3, then add one, and you get 196/3 pi in^3.
