Question

If two angles are suplementary and one angle is 30 less than twice the measure find the angles

Answer 1

Let one angle be x

The measure of other angle = 2x-30

Sum of the angles = 180

= 2x-30+x = 180

= 3x = 210

= x = 70°

And the other angle is 110°

Answer 2

Step-by-step explanation:

let one angle be x.

measure other angle =2x -30

sum of angle =180

2x-30+x=180

3x=210

x=70

and the other angle = 180-70=110 ans
