Question 945345: In parallelogram abcd, the degree measure of angle a is represented by 2x and the degree measure of angle b by 2x + 60. Find the value of x. Answer by amarjeeth123(570) (Show Source):
You can put this solution on YOUR website! In a parallelogram consecutive angles are supplementary.
a+b=180 degrees
2x+2x+60=180
4x+60=180
4x=120
x=30
