Question

two adjacent angles of a parallelogram in ratio of 2 : 3. find the measure of all the angles

Answer 1

Sum of 2 adjacent angles of a parallelogram id 180 degree.
2x+3x=180
5x=180
x=180/5
x=36
So all the angles of a parallelogram are 72,108,72 and 108 degrees.

Answer 2

two adjacent angles measure is 180°
therefore let the two angles be 2x and 3x
so, 2x+3x= 180°
5x=180°
x= 180/5
= 36°
therefore the angles are
36(2) = 72° and 36(3) =108°.

and thus the four angles are 72,108,72,108.

hope it helps!
