Answer:
Let the measures of two adjacent angles, ∠A and ∠B, of parallelogram ABCD are in the ratio of 3:2.
Let ∠A = 3x and ∠B = 2x
We know that the sum of the measures of adjacent angles is 180º for a parallelogram.
angle A + angle B =180
3x + 2x = 180
5x =180
x =180/5
x = 36
A = ∠C = 3x = 108º (Opposite angles)
∠B = ∠D = 2x = 72º (Opposite angles)
Thus, the measures of the angles of the parallelogram are 108º, 72º, 108º, and 72º.

Answer:
108°, 72°
Step-by-step explanation:
Since the adjacent angles of a parallelogram are supplementary (meaning the angles make a sum of 180°) we will add the ratios 3+2=5.
1st angle= 3/5*180
= 108°
2nd angle= 2/5*180
= 72°
