Easyslope distancehorizontal distance
A slope distance of 150.00 m is measured at a vertical angle of 8°. The horizontal distance is most nearly:
- A148.54 m
- B20.88 m
- C150.00 m
- D151.47 m

Answer: A. 148.54 m
Equation: horizontal distance H = S cos α. Values: slope distance S = 150.00 m, vertical angle α = 8°. Step 1: cos 8° = 0.99027. Step 2: H = 150.00 × 0.99027 = 148.54 m. 20.88 m is the vertical component S sin α; 151.47 m divides by cos α; 150.00 m applies no reduction.
