Answer:

126

Explanation:

The exterior angle is the sum of the opposite interior angles

x+ 84 = 3x

Subtract x from each side

84 = 2x

Divide by 2

84/2 = x

42 =x

We want angle FEG = 3x

FEG = 3x

FEG = 3*42

FEG = 126

Answer:

D. 126 degrees

Explanation:

angle FEG is the sum of interior angles D and G.

3x = x + 84

subtract x from both sides

2x = 84

divide by 2 from both sides

x = 42

3x = 3(42) = 126
