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 )
