Answer 2

Answer:

100 degree, 80 degree

Step-by-step explanation:

One angle is =5x and the other angle=4x

We know that two adjacent angles on a straight line always forms a linear pair:

= 5x + 4x = 180 degree

= 9x = 180 degree

     x= 20 degree

Therefore one angle =5x=5 x 20 = 100

and other angle =4x=4 x 20 = 80.

5x = 100 degree

4x = 80 degree
