Question 210604: I need help with these two, they're not in the textbook (GEOMETRY) they're on a review sheet I have to do to prepare for our test tomorrow.
#1) The measure of the supplement of an angle is 32 less than the measure of the angle. Find the measures of the angles.
#2)The measure of one angle is 12 degrees greater than the measure of its complement. What are the measures of the angles?
PLEASE HELP! Thanks!

You can put this solution on YOUR website! #1) Let the angle be A, then:
180-A = A-32 "...the supplement of an angle (180-A) is 32 degrees less than the measure of the angle."
180 = 2A-32
212 = 2A
A = 106 degrees and its supplement, 180-A = 74 degrees.
#2) Let the angle be B, then:
B = (90-B)+12 "The measure of one angle (B) is 12 degrees greater than the measure of its complement (90-B)."
B = 78-B Add B to both sides.
2B = 78 Divide both sides by 2.
B = 39 and its complement, 90-B = 51 degrees.
