Question

Find the measure of angle P in the triangle below. Please help!!

Answer 1

sin (P) = 48 / 60
sin (P) = .8

arc sin (.8) = 53.13 degrees

Answer 2

thank you!! can you help me with the follow up question?

Answer 3

using the value found iin the previous problem find the measure of angle R and the measure of angle Q

Answer 4

wait I just realized these questions are in Law of cosine section so do I have to use cos?

Answer 5

r will the answer still be the same?

Answer 6

or*

Answer 7

Angle Q is 90° because that is a 3 - 4 - 5 triangle and are always right triangles.
Angle R is 90° - 53.13° = 36.87°
I don't know why they start talking about law of cosines considering that was all done without using it.

Answer 8

ok thank you so much!

Answer 9
