Question

what is the value of r? (diagram with angle 53.4° and angle r)

Explanation:

Step1: Assume the angle is bisected (common in such diagrams)

If the two angles formed by the middle ray are equal (bisecting a right angle? Wait, maybe it's a right angle total? Wait, maybe the total angle is 90 degrees? Wait, maybe the diagram is a right angle split into r and 53.4°. So total angle 90°, so r + 53.4° = 90°.

Step2: Solve for r

r = 90° - 53.4° = 36.6°

Answer:

36.6°
