Question

Find the angles of a parallelogram ABCD in which ZA = 2 ZB.​

Answer 1

Answer:

120°, 60°, 120° and 60°

Step-by-step explanation:

Angle A = 2 Angle B

Angle A and Angle B are adjacent angles.

=> Angle A + Angle B = 180°

=> 2B + B = 180°

=> 3B = 180°

=> B = 180 ÷ 3

=> Angle B = 60°

Angle A = 120°

Angle C = 120°

Angle D = 60°
