Question

If two adjacent angles of a parallelogram are in the ratio 4:5. Write the measure of its greatest angle

Answer 1

Answer:

100°

Step-by-step explanation:

The two adjacent angle of parallelogram make up 180°.

Therefore, 4x+5x=180

                  9x=180

                   x=20

So, the measure of greatest angle is 5x=5×20=100°.....
