Answer:

Step-by-step explanation:
<u>Equation Solving</u>
We are given the equation:

It's required to solve it for a.
Swap sides to have the letter on the left side:

Divide by
:

- linear pairs are supplementary, meaning they add up to 180°
5x + 9 + 3x + 11 = 180
8x + 20 = 180
8x = 160
x = 20
- now plug in.
angle 1: 5(20) + 9 = 100 + 9 = 109°
angle 2: 3(20) + 11 = 60 + 11 = 71°
