Question

The adjacent angles of a parallelogram are in the ratio 4:5, Find the measure of the smallest angle​

Answer 1

Answer:

80 deegrees

Step-by-step explanation:

The sum of adjacent angles of a parallelogram is 180 degrees.

4x + 5x = 180

9x = 180

x = 180/9

x= 20

Therefore, the smallest angle is 4x. So, 4x= 4 x 20=80
