Answer 2

$Question$

Find the angles.

$Condition$

The two angles are to the ratio 9:11

$Answer$

First angle = 81 degree

Second angle = 99 degree

$Explanation$

At first add the two ratios which equals to 20, now as you can see we have to write 9/20 x 180

( I am first doing the 9 you can also do the 11 first)

The answer of 9/20 x 180 is 81 degree. So as you know supplementary angle is 180 degree. Then if 1 angle is 81 degree another angle will of course be 180 degree - 81 degree.

Hope it helps!
