Question

If an angle of a parallelogram is two third of its adjacent angle ,find tha angles of the prallelogram

Answer 1

Let the angle be 'a'

adjacent angle be 2a/3

Sum of adjacent angles in parallelogram is 180°

so,

a + 2a/3 = 180

( 3a + 2a ) / 3 = 180

5a = 540

a = 108°

2a/3 = 72°


angles are 108° & 72°
