Two angles are complementary is the sum of their measures is 90 degrees. the measure of the first angle is 12 degrees more than 4 times the second angle. find the measure of the first angle.

Using the information given you can set up an equation to find the angle.
Let x = Second angle
Let 4x + 12 = First angle
Angle 1 and 2 should add together to equal 90°. The equation therefore is ,





However the value of x is not for the first angle, it is the value for the second angle. Putting this value unto the first angles equation will give us the actual angle.



The first angle is 93.6°.
