Answer

Angle 1 = 109°

Angle 2 = 71°

Step-by-step explanation

We are told that Angle 1 and 2 form a linear pair. This means that they sum up to give 180°.

Angle 1 = 5x + 9

Angle 2 = 3x + 11

(Angle 1) + (Angle 2) = 180°

5x + 9 + 3x + 11 = 180°

8x + 20° = 180°

8x = 180° - 20°

8x = 160°

Divide both sides by 8

(8x/8) = (160°/8)

x = 20°

Angle 1 = 5x + 9 = 5 (20°) + 9° = 100° + 9° = 109°

Angle 2 = 3x + 11 = 3 (20°) + 11 = 60° + 11° = 71°

Hope this Helps!!!
