Answer:

30°

Step-by-step explanation:

Solve the blank angle for the bottom triangle. The sum of all the angles of a triangle is equal to 180. 75° + 75° = 150°. 180° - 150° = 30°. The missing angle of the bottom triangle is 30°. Angle x is equal to the blank angle of the bottom triangle. Therefore, x = 30°.
