1) The measure of one angle is three times the measure of its complement. Find the measure of each angle.
2) The measure of one angle is 38* less than the measure of its supplement. Find the measure of each angle.

You just need to memorize what the words mean. Complement and supplement are used all the time, so learn them perfectly.
1) The measure of one angle is three times the measure of its complement.
3x = 90 - x The rule is you can do any valid operation on both sides of an equation and it will still be equal. Add x.
4x = 90 Divide by 4.
x = 22.5, 90 - x = 67.5
2) The measure of one angle is 38* less than the measure of its supplement.
x+ 38 = 180 - x Solve the same way.
Thank you so much for the help!
