Two unequal angles of a parallelogram are in the ratio 2: 3. Find all its angles in degrees.
Let A = 2x and B = 3x
Now, A +B = 180 [Co-interior angles are supplementary]
2x + 3x – 180 [AD II BC and AB is the transversal)
⟹ 5x = 180
x = 180/5
x = 36
Therefore, A = 2 × 36 = 72
b = 3 × 36 = 108
Now, A = C = 72 [Opposite side angles of a parallelogram are equal)
B = D = 108
