What is measure of angle r?

enter your answer as a decimal in the box. round only your final answer to the nearest hundredth.

To find an angle you need to use trig ratios (tan, sin, and cos).

In this case to find ∠R you would need to use sin or cos because both of the legs are not across or adjacent to it.

To find ∠R you would need to do the "opposite" formula which would be (for sin) 5/13 ≈ 0.38.. asin = 22.26

Gotta be d the music of previous eras
