Question

Write and solve an equation to find the complement of a 42 degree angle. tell what the variable represents.

Answer 1

The complememtn is the angle that adds to the angle to get 90

so

the complement of angle a is b if
a+b=90

so

the comlmement of a 42 degree angle is
42+complement=90
complmement=c
42+c=90
minus 42 both sides
c=48

the measure of the complement is 48 degrees
c is the complement
