Question

20 points!! pls help

In the triangle below, you are given two measurements. What ONE other measurement would you need in order to use the Law of Sines? (There is more than one possible answer.)

Answer 1

Answer: You would either need ∠C or side b.

Explanation:

To use the law of sines, you would have to have both the corresponding angle and side length (side b and angle B, for example). We already have ∠B and side c, so to use the law of sines, we would need the corresponding angle for side c (∠C), or the corresponding side for ∠B (side c).

Answer 2

You would either need side a and its angle, side b, or <C. Either of these corresponding dimensions would work in the Law of Sines.

I hope this helps, and as always, I am joyous to assist anyone at any time.
