Answer:

See explanation

Explanation:

Given


\angle 1 = 4x - 7


\angle 2 = 3x + 9

Required

Find x

The question is incomplete, as the relationship between both angles is not given

(1) If they are supplementary, then


\angle 1 + \angle 2 = 180


3x + 9 + 4x - 7 = 180

Collect like terms


3x + 4x = 180+7-9


7x = 178

Divide both sides by 7


x = 25.43

(2) If they are complementary, then


\angle 1 + \angle 2 = 90


3x + 9 + 4x - 7 = 90

Collect like terms


3x + 4x = 90+7-9


7x =88

Divide both sides by 7


x = 12.57

(3) If they are vertically opposite angles, then


\angle 1 = \angle 2

So, we have:


4x - 7 = 3x + 9

Collect like terms


4x - 3x = 9 +7


x = 16
