  • sin∅ = opposite over hypotenuse

Explanation:

Step 1: Define

∅ = 40°

opposite leg of angle = 50 ft

hypotenuse = x ft

Step 2: Solve for x

  1. Substitute: sin40° = 50/x
  2. Multiply x on both sides: xsin40° = 50
  3. Divide sin40° on both sides: x = 50/sin40°
  4. Evaluate: x = 77.7862
  5. Round: x = 77.8 ft
