Question

Two adjacent angles of a parallelogram are in the ratio is 4:5. Find the measure of each angle

Answer 1

Answer: 80 degree , 100 degree

Step-by-step explanation:

Sum of adjacent angles of a parallelogram = 180

Given ratio = 4 : 5

4 X + 5 X = 180

9 X = 180

X = 180/9= 20

Angles are : 4*20 , 5*20 = 80 , 100
