Answer: C. 28°
Explanation:
Two angles are complementary when they add up to 90 degress.
You have two angles. A & B
Equation 1: A+B=90
Equation 2: A+34=B
Solve equation 1 for one of the variables
I solved for A
A=90-B
Now plug (90 - B) into equation 2 for A
(90-B)+34=B Simplify
124-B=B Add B to both sides
124=2B Divide both sides by 2
62=B
Now plug 62 into equation 1 for B
A+62=90
A=28
