WebTo solve triangles by Law of Sine given two sides and an opposite angle, consider the following steps below: Find the other opposite angle using the Law of Sines. Determine for the possible solutions of triangle if it is possible to be an acute or obtuse triangle. Determine the remaining unknown angle by subtracting the two known angles from 180°. WebJan 2, 2024 · Solution Using the Law of sines, we can say that: sin112 ∘ 45 = sin B 24 0.9272 45 ≈ sin B 24 24 ∗ 0.9272 45 ≈ sinB 0.4945 ≈ sinB Then, we find sin − 1(0.4945) ≈ 29.6 ∘. Remember from Chapter 3 that there is a Quadrant II angle that has sinθ ≈ 0.4945, with a reference angle of 29.6 ∘. So, ∠B could also be ≈ 150.4 ∘.
