Question

Solve for the short leg of the 30-60-90 triangle.

Answer 1

2

Explanation:

The basic 30-60-90 triangle ratio is:

Side opposite the 30° angle: x

Side opposite the 60° angle: x√3

Side opposite the 90° angle: 2x

Here, the side opposite the 90° angle is 4.

This means that 2x = 4 and, thus, x = 2.

Since b is the side opposite the 30° angle, b = x, so it is 2.
