Question

two supplementary angles are in ratio 2:7. how do i find the angles.

Answer 1

Two angles are in the ratio 2:7

so if x is some number, then we have the two angles 2x and 7x

The angles are also supplementary, that means they add to 180 degrees

2x+7x = 180

Answer 2

solve that for x, then use that value of x to find 2x and 7x

Answer 3

2 supplementary angles have to add up to 180 degrees
