Answer:
14°
Step-by-step explanation:
Both angles are vertical angles and are opposite, hence, from angle theorem., vertically opposite angles are equal :
Angle EGD = Angle FGH
Angle EGD = (4x + 8)
Angle FGH = 64
HENCE,
4x + 8 = 64
4x = 64 - 8
4x = 56
x = 56/4
x = 14°
Move the -7 to the right, its sign will flip (do you know why?)
Negate both sides to change -x to x
-x = 16+7
-x = 23
x = -23
