Law of sines

Step-by-step explanation:

Given: 1 angle and 2 sides

To use law of sines you need either two sides and the non-included angle or two angles and the non-included side.

We're given two sides and the included-angle.

Law of Sines, two sides and an opposite angle are included.

Step-by-step explanation:

The law of sines is denoted by the following formula:

sin(a)/A = sin(b)/B = sin(c)/C

This is a formula relating the side lengths of any triangle to the sines of their angles. You will always have to divide the opposite of an angle to it's corresponding opposite side of the triangle. Since ∠R and the side lengths of r and q are given, we can apply the law of sines to get this equation: sin(R)/r = sin(Q)/q  where Q is the only unknown factor.

*REMINDER: Don't even consider the law of cosines because it's only useful to find an unknown angle measure or third side of a triangle when we are given two sides and an angle between those two sides.
