SOME GEOMETRY

1. The supplement of an angle is four times the complement of the angle. Find the measure of the complement.

Step 1. Supplement is when two angles add up to 180 degrees or A+B=180

where A be one angle and B be the other complementary angle.

Step 3. A=4B (supplement of an angle is four times the complement of the angle)

Step 4. Substitute A=4B into Step 1.

180=A%2BB=4B%2BB=5B

180%2F5=5B%2F5=B


B=36

A=180-36=144
