Question

PLEASE HELP ME WITH THIS

What is the measure of ∠P?

Round your answer to the nearest degree.

a. 29°
b. 42°
c. 65°
d. 78°

Answer 1

In this question , we have to use sine law, which is

`(sin \ Q)/(PR) = (sin \ P)/(QR)`

`(sin73)/(68) = (sin \ P )/(47.6)`

`sin \ P = (47.6 sin 73)/(68)`

`P = sin^(-1) ( ( 47.6 sin73)/(68)) = 42`

Correct option is b.
