Two angles are complementary If the measure of one angle is 20 more than the measure of the second angle what is the number of degrees in the measure of the smaller angle?

first you have to change this into equation by "translating" it into math. so

let x= the first angle

90-x ( because complementary means they add up to 90) = the second angle

x= (90-x) + 20

x+x = 90-x+20+x

2x = 90-20

2x = 70

x = 35

the smaller angle = 35 degrees
