Answer 1

Answer:

80 and 100 will be answer.

Answer 2

Answer:First angle=20×4=80

Second angle=20×5=100

Explanation:

Sum of adjacent angles of  parallelogram=180°

two adjacent angle of parallelogram are in the ratio of 4 is to 5.

4x+5x=180

9x=180

x=20

First angle=20×4=80

Second angle=20×5=100
