PLEASE HELP ASAP!!! I NEED CORRECT ANSWERS ONLY PLEASE!!!

Answer 1

Answer:

$m\angle R=69.4^o$

Step-by-step explanation:

we know that

In the right triangle PQR

$tan(R)=\frac{PQ}{QR}$ ----> by TOA (opposite side divided by adjacent side)

substitute the given values

$tan(R)=\frac{8}{3}$

using a calculator

$m\angle R=tan^{-1}(\frac{8}{3})=69.4^o$
