Question

A parallelogram has one angle that measures 150°. What are the measures of the other three angles in the parallelogram?

Answer 1

150 degree is opposite angle and remaining angle is 30 degree

Answer 2

let angle a be 150°
angle c = 150°( opposite angle)

angle b =180°-150° = 30° ( adjacent angle)
angle d = angle b ( opposite angle)
angle d = 30°
