Q20 of 95 Page 15

If an angle of a parallelogram is two-third of its adjacent angle, the smallest angle of the parallelogram is

Given,


In parallelogram ABCD


∠A+∠B = 180° [adjacent angles of parallelogram are supplementary]



∠ A =


So,


=


=


∠A =


Thus smallest angle of parallelogram is 72°
