Two angles are supplementary.One angle measures 2 more than 3 times the other angle.what is the measure of each angle?

the wall, ground, and ladder form a righ triangle, with the ladder as hypotenuse, so,
x^2 + 4^2 = 12^2
supplementary angles add up to 180 degrees. So,
x + 3x+2 = 180
one angle is x, the other is 3x+2. Solve for x, and you're almost there.
