Answer:
x = 60°
Step-by-step explanation:
First, note that the 30° angle and Angle CGE are vertical angles; therefore, Angle CGE is also a 30° angle.
Next, note that Angles CGE and x are complementary angles; that is, they sum up to 90°.
Subtracting Angle CGE (a 30° angle) from 90° yields 60°. This is the desired answer: x = 60°
