Question

Two consecutive angles of a parallelogram are in the ratio 4 : 5. Find the measure of all angles.​

Answer 1

Answer:

If n(A) = 55 n(B)- 62 n(AUB) 15 then in C(AUB)

Answer 2

Answer:

Two adjacent angles of a parallelogram are in the ratio 4:5. Find their measures. Solution : Let the angles be 4x and 5x. Then, 4x + 5x = 180° 9x = 180° x = 20° So, angles are 4 × 20° = 80° and 5 × 20° =100°.
