WebThe Law of Cosines is useful for many types of applied problems. The first step in solving such problems is generally to draw a sketch of the problem presented. If the information given fits one of the three models (the three equations), … WebUsing the right triangle relationships, we know that sinα = h b and sinβ = h a. Solving both equations for h gives two different expressions for h. h = bsinα and h = asin β. We then set …
