Question

A 7 foot long board is propped against the wall of a house. The board forms a 60 angle with the ground. How far is the base of the board from the wall?
A. 3.5 ft

B. 3 ft

C. 2.5 ft

D. 4 ft

Answer 1

This is like a 30-60-90 triangle with a hypotenuse of 7. Since the relationship of the base to the hypotenuse in a 30-60-90 triangle is 1:2, the answer is 7/2=3.5 ft. Hope this helps!
