Question

I have no idea what I am doing

Answer 1

You have to find the measure of angle QPR.

Solve:

`40 = 8x + 7 + 9x + 16`

Add like terms

`40 = 17x + 23`

Solve

`40 - 23 = 17x + 23 - 23`

`17 = 17x\\(17)/(17) = (17)/(17)x\\1 = x`

Plug in x to solve for the angle measure of QPR

`9(1) + 16 =\\9 + 16 =\\25`

The angle measure of QPR is 25°

Answer 2

QPR = 30 degrees
