The measure of the supplement of an angle is three times the measure of the complement. Solve for the angle.

I just want to find the equation but I do not understand it. I know that the angle is 40 degrees. Please teach me how to find the equation

If two angles are complementary, they add to 90.

if two angles are supplementary, they add to 180.

So, if your angle is x, then its supplement is (180-x), and its complement is (90-x).

Now you can derive the needed equation and solve it.

oh, yeah. The angle is <u>not</u> 40°
