Law of Sines - Wyzant Lessons

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 the expressions equal to each other. bsinα = asinβ ( 1 ab)(bsinα) = (asinβ)( 1 ab) Multiply both sides by 1 ab. sinα a = sinβ b. WebThe law of sines formula allows us to set up a proportion of opposite side/angles (ok, well actually you're taking the sine of an angle and its opposite side).

WebNov 2, 2024 · The Law of Sines is based on proportions and is presented symbolically two ways. (8.1.1) sin α a = sin β b = sin γ c (8.1.2) a sin α = b sin β = c sin γ To solve an oblique triangle, use any pair of applicable ratios. Example 8.1. 1: Solving for Two Unknown Sides and Angle of an AAS Triangle WebBecause the angles in the triangle add up to 180 degrees, the unknown angle must be 180° − 15° − 35° = 130°. This angle is opposite the side of length 20, allowing us to set up a Law of Sines relationship. sin(130 ∘) 20 = sin(35 ∘) a asin(130 ∘) = 20sin(35 ∘) a = 20sin(35 ∘) sin(130 ∘) a ≈ 14.98.
