Answer:
C
Step-by-step explanation:
Find the height (h ) above eye level and add 5 to give height from floor level.
Since the triangle is right use the tangent ratio to find h
tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{h}{5}[/tex]
Multiply both sides by 5
5 × tan60° = h, hence
h ≈8.66
The height is 8.66 + 5 = 13.66 ≈ 14 ft ( to nearest foot )
