Question

Triangle PQR: Find measure of Angle P

30.4°

35.9°

59.6°

54.1°

Answer 1

I'm not sure how to find <P using the 2 sides? Would you use SOHCAHTOA?

Answer 2

In relation to angle P is QR the side opposite, the side adjacent or the hypotenuse?

Answer 3

Opposite, i'm pretty sure.

Answer 4

Because wouldn't PQ be the adjacent and PR be the hypotenuse?

Answer 5

Yes. In relation to angle P is PR the side adjacent, the side opposite or the hypotenuse?

Answer 6

So. You are trying to find the angle P. You know the side opposite and the hypotenuse. What function does that suggest? sin, cos, or tan? opposite...hypotenuse

Answer 7

Sine?

Answer 8

yes. So write:
\[\sin P=\frac{side opposite}{hypotenuse}\]

Answer 9

sin<P = 33.8/57.6

Answer 10

fill in the numbers that you know.

Answer 11

Yes.

Answer 12

Would you divide the two then?

Answer 13

yes. And then hit your inverse sin button. That will give you the angle.

Answer 14

35.9 :) Thanks a lot, again ^_^

Answer 15

Yep. That's what I got.
