Question

Find the measures of two complementary angles if the difference in their measures is 18

Answer 1

54 and 36

Explanation:

Two angles are complementary if they add up to 90°

let x be the 1st angle and y be the 2nd angle

x+y=90

the difference is 18

x-y=18

add the 2 equations

x+y=90

x-y=18

---------

2x = 72

x = 36

y = 54
