Finding unknown lengths of triangles
WebThe unknown length is on the bottom (the denominator) of the fraction! So we need to follow a slightly different approach when solving: Start with: sin 68° = 70/w Multiply both sides by w: w × (sin 68°) = 70 Divide both sides by "sin 68°": w = 70 / (sin 68°) Calculate: w = 70 / 0.9271... w = 75.5 m to 1 decimal place The length of the wire = 75.5 m WebJun 3, 2024 · This trigonometry video tutorial explains how to calculate the missing side length of a triangle.
