Q31 of 160 Page 144

If two angles of the parallelogram are in the ratio 2:3, then the measure of angles are

Let the angles be 2x, 3x


The adjacent angles of a parallelogram are always supplementary and the opposite angles are always equal


2x + 3x = 1800


⇒ 5x = 1800


⇒ x = 360


So, the angles are


2× 36 = 720


3× 36 = 1080
