WebUses the law of cosines to calculate unknown angles or sides of a triangle. In order to calculate the unknown values you must enter 3 known values. To calculate any angle, A, B or C, enter 3 side lengths a, b and c. This is the … WebMay 9, 2024 · Using the right triangle relationships, we know that sin α = h b and sin β = h a . Solving both equations for h gives two different expressions for h. h = bsin α 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
Finding an Angle in a Right Angled Triangle
