Question

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

Find m∠R.

Write your answer as an integer or as a decimal rounded to the nearest tenth.


m∠R = °

Answer 1

`m\angle R=69.4^o`

Explanation:

we know that

In the right triangle PQR

`tan(R)=(PQ)/(QR)` ----> by TOA (opposite side divided by adjacent side)

substitute the given values

`tan(R)=(8)/(3)`

using a calculator

`m\angle R=tan^(-1)((8)/(3))=69.4^o`
