Question

The measure of two adjacent angles of a parallelogram are in the ratio of 4 : 5 .Find the measure of each angle of the parallelogram . plz solve it​

Answer 1

80 degree and 90 degree

Answer 2

Answer:

80

100

Step-by-step explanation:

let the common ratio be x

hence angle1=4x and angle2=5x

so 4x+5x =180 (adjacent angles of ||GM are supplementary)

9x=180

x=20

hence angle 1= 4×20=80

angle 2 = 5×20=100
