Question

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

Answer 1

Answer:

let the angles be 4x and 5x

4x+5x=180° (adjacent angles)

=9x=180

=x=180/9

=x=20

therefore,4x=4*20=80°

5x=5*20=100°

measure of each angle=80°, 100°, 80°, 100°

{the given adjecent angles are the opposites of the other angles of the parallelogram}
