what is the value of r? 53°

Explanation:

Step1: Identify angle - relationship

The two angles 53° and r are complementary (form a right - angle which is 90°).

Step2: Set up the equation

Let the sum of the two angles equal 90°. So, 53°+r = 90°.

Step3: Solve for r

r=90° - 53°.
r = 37°

Answer:

37
