Question

The measure of one of the supplementary angles is twice the other. Find the measures of the angles.​

Answer 1

Answer:

let the angles are x,2x.

x+2x=180

3x=180

x=60

Answer 2

overview: we need to find the angles

Note: Supplementary angles add to 180 degrees

step 1) Clear up the data given

1st angle = (?) = let it be x

2nd angle = (?) = let it be 2x as 2nd angle is double than the first one

sum of both = 180

step 2) Form equation and then solve it

x+ 2x =180

3x = 180

x = 180 / 3

x = 60

2x = 60 * 2 = 120

step 3) we have got our answer

1st angle = 60

2nd angle = 120
