Question

one of the angle of parallelogram is 60° more than its adjacent angle find the all angles​

Answer 1

Step-by-step explanation:

Let one angle be x then the other angle will be x+60.

So, x+x+60°=180°

=> 2x+60°=180°

2x=180°-60°

2x=120°

x=60°

Therefore,all the angles of the parallelogram are 60°,120°,60°and 120° .
