Question

What is the length of the hypotenuse of a 30-60-90 triangle if the short leg has a length of 10?

Answer 1

Answer: 20

Explanation:

30-60-90 triangles are special: Their side lengths fall in a ratio of 1:2:
`√(3)`, in order of Shortleg : hypotenuse : longleg

Since we know the short leg is 10, the hypotenuse must be double, or 20.
