two angles are complimentary. The sum of the measure of the first angle and half the second angle is 75 degrees. Find the measure of the angles.
What is the measure of the smaller angle?
what is the measure of the other angle?

x + y = 90
x + .5y = 75

.5 y = 15
y = 30 etc 
In any triangle, the sum of the measures of the angles is 180degrees. In triangle ABC, angle A is four times as large as angle B. Angle C measures 20degrees less than angle B. Find the measure of each angle.
