WebThe calculator solves the triangle given by two sides and a non-included angle between them (abbreviation SSA side-side-angle). The SSA (Side-Side-Angle) theorem is a statement in geometry that states that if two sides of a triangle have a given ratio to two sides of another triangle and the included angle between those sides is the same in both … WebDec 11, 2024 · Because 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 ∘) ≈ 14.98.
