Question

If one of a parallelogram is two-third of its adjacent angles find all angles

Answer 1

Let the angle be x.

Given, x + 2/3 x = 180
 
            5x/3 = 180

            5x= 540

             x = 108

So, 2/3 * x = 2/3 * 108

                  = 72


Angles are 72,108.

Answer 2

Let one angle be x and other be2/3x
x+2/3x=180
5x/3=180
5x=540
x=108
2/3x=72
