Question

If one angle of a parallelogram is 30° less than twice the smallest adjacent angle then find the
measure of each angle.​

Answer 1

Answer:

Let the smallest angle be x

One angle = 2x - 30°

∴ x + 2x - 30° = 180°

⇒ 3x = 210°

⇒ x = 70°

∴ 2x - 30° = 110°

∴ Angles are 70°, 110° , 70°, 110° ...
