Question

The supplement of an angle is 15 degrees more than twice the measure of the angle itself. How do you find the angle?

Answer 1

the requested angle is 55 degrees

Explanation:

If x is the requested angle, you can say that its supplement is 180-x;
it also is 15+2x, or:

`180-x=15+2x`

that is equivalent to:

`2x+x=180-15`

`3x=165`

`x=165/3=55`
