Horizontal Distance from Slope Distance
Easytrigonometryslope distance
A slope distance of 100 m is measured at 10° above the horizontal. What is the approximate horizontal distance?
- A90.0 m
- B96.6 m
- C98.5 m
- D100.0 m
Show solutionHide solution
Answer: C. 98.5 m
Horizontal distance is the adjacent component: H = S cos θ = 100 cos 10° = 98.48 m, approximately 98.5 m.
