Law of sines khan
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. WebThe Law of Sines just tells us that the ratio between the sine of an angle, and the side opposite to it, is going to be constant for any of the angles in a triangle. So for example, for this triangle right over here. This is a 30 degree angle, This is a 45 degree …
