Question

The longer leg of a 30°-60°-90° right triangle measures 5 in. What is the length of the shorter leg?

Answer 1

The figure shows the ratios of the lengths of the 3 sides of a 30-60-90 triangle.
The long leg is sqrt(3) times longer than the short leg.
The hypotenuse is twice the length of the short leg.

Answer 2

It's triangle a = 4.33   b = 2.5   c = 5

Answer 3

An angle lying opposite to a bigger triangle side is also a bigger angle-> so c=5 is hypotenuse

Answer 4

Simply answer is x=5 sin 30 = 2.5
