If they are in the ratio of 4:5, that means they will have measurements of 4x and 5x.

And since they are a linear pair, that means they are supplementary (they add up to 180°)

4x + 5x = 180°

9x = 180°

x = 180°/9

x = 20°

So the angles are:

4x = 80°

5x = 100°

Answer 2

Step-by-step explanation:

Let the first angle be 4x

second angle= 5x

sum of linear angles = 180

ATQ

4x + 5x= 180

9x= 180

x= 20.

first angle = 4x= 80

second angle = 5x= 100.
