Geometry. Please help.

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.
Thank you!!!(= I get it now
You're very welcome. :-)
THE MEASURE OF ONE ANGLE IS 15 DEGREES MORE THAN HALF THE MEASURE OF ITS COMPLEMENT. FIND THE MEASURE OF THE TWO ANGLES
Melanie your stupid for knowing that(No offense :/)
But I was going to say the same thing Ms.Sue was going to say.
The measure of a third angle in an isosceles triangle is 82.5 more than the measure of the two equal angles. whats the angle of the third.
an angle is 35 degrees more than triple its supplement. find the measures of the angles
