Question

The longer leg of a 30-60-90° triangle is 18. What is the length of the other leg?

A) 1213
B) 93
C) 9
D) 63

Answer 1

D

Explanation:

In a 30-60-90 triangle, the longer leg is
`√(3)` times larger than the smaller leg. The length of the shorter leg is therefore:

`(18)/(√(3))= \\\\\\(18√(3))/(3)= \\\\\\6√(3)`

Hope this helps!
