Answer:

C - 20 feet

Step-by-step explanation:

Use Trigonometry

a^2 + b^2 = c^2

Visualise this as a triangle. The height of the triangle is 16 feet and the base of the triangle is 12 feet. All we need to find is the slant height (which is the ladder).

16^2 + 12^2 = c^2

c = [tex]\sqrt{400}[/tex]

c = 20
