Question

Look at the tree shown in the diagram. What is the bight of the tree rounded to the nearest tenth foot?

Answer 1

Correct answer is B, 69.3 feet

Explanation:

Since we have a 30°-60°-90° right triangle, the length of the longer leg is √3 times the length of the shorter leg, so the length of the shorter leg is 1/√3, or √3/3 times the length of the longer leg.

`120( ( √(3) )/(3)) = 40 √(3) = 69.3`
