Question

A ladder leans against a building, forming an angle of 60° with the ground. The base of the ladder is 6 feet from the building. What is the length of the ladder?

A) 6.93
B) 12 ft
C) 11.68 ft
D) 10.39 ft

Answer 1

12 ft

Explanation:

There are 2 known angles in the right triangle (90: because the building is perpendicular to the ground, and 60) which means the third angle is 30.

The side of the triangle that is across from the 30 degree angle is HALF the one across from the 90 degree angle. Which means the lengthy is 6*2 and that equals 12.
