Question

if 4x degree and 5x degree from a linear pair find them

Answer 1

Given that,
Angle 4x and 5x form a linear pair.

We know that two angels which forms linear pair then their sum will always = 180 degree

So, 4x+5x = 180
9x = 180
x= 180/9
x= 20 degree

First angle = 4x
= 4 multiply by 20
= 80 degree

Second angle = 5x
= 5 multiply by 20
= 100 degree

Therefore, two angles= 80 and 100 degree.

Glad to help.
