1) Two angles are complementary. The measure of one angle is 21 more than twice the measure of the other angle. Find the measure of the angles.

2) If a supplement of an angle has a measure 78 less than the measure of the angle, what are the measures of the angles?

Please don't just give me the answers, but tell me how you got them. Thank you.

1) Complementary angles add up to 90 degrees.

Let x = the smaller angle. Solve for x.

x + 2x + 21 = 90

2) Supplementary angles add up to 180 degrees.

Take it from there.
