The measure of the supplement of an angle is 30 more than twice the measure of the angle. find the measure of the angles

Triangle = 180 degrees

Angle = 37.5 degrees

Supplement angle = 105 degrees

If you multiply the angle (37.5) by 2 and then add 30, it gives you 105. Then add 37.5 twice to make up the other two angles of the triangle and it gives you 180 total degrees as a triangle should.
