WEBThe Law of Sines can be used to solve for the sides and angles of an oblique triangle when the following measurements are known: Two angles and one side: AAS (angle-angle-side) or ASA (angle-side-angle) Two sides and a non-included angle: SSA (side-side-angle) Example: For triangle ABC, a = 3, A = 70°, and C = 45°. Find B, b, and c.

The Law of Sines - Math Open Reference
WEBThe Law of Sines says that in any given triangle, the ratio of any side length to the sine of its opposite angle is the same for all three sides of the triangle. This is true for any triangle, not just right triangles.

WEB\[ \frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c} \] Sometimes it is handy to set up a problem with the side lengths in the numerator: The Law of sines \[ \frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C} \]\ Solve the triangle. Round side lengths to the nearest \(100^{\text {th }}\). In this problem we're given two angles and one side.
