The measure of two adjacent angles of a parallelogram are in the ratio 3:2. Find the measure of each of the angles of the parallelogram.

Let two adjacent angles be 3x and 2 . x
Since the adjacent angles in a parallelogram are supplementary.
∴ 3x+2x=180°
⇒ 5x=180°/5=36°
∴ One angle = 3x=3×36°=108°
and another angle = 2x= 2×36° =72°
