Question

if an angle of parallelogram is two third its adjacent angle find the angle of the parallelogram​

Answer 1

Answer:

Let the adjacent angle be x

then the angle = 2/3 x

We know that the sum of adjacent angle of a llgm is 180°

x + 2x/3 = 180

(3x + 2x)/3 = 180

5x = 540

x = 540/5 = 108°

Hence the adjacent angle = (2 × 108)/3

= 72°
