two angles are complementary. the sum of the measure of the first angle and half the second angle is 87 degrees. find the measure of the angles. What is the measure of the smaller angle?
what is the measure of the other?
Angle A + Angle B = 90º(complementary)
Therefore A = 90º - B
A + .5B = 87º
Substitute 90º - B for A in last equation to solve for B. Put that value in the first equation to find A. Check by putting both values in the last equation.
