Which triangle is a 300-60°-90° triangle?
10
5/3
15
5/3

Check the picture below.

A)

Step-by-step explanation:

The 30-60-90° triangle has the side lengths of 1, √3, 2, so you should find the triangle that fits this measurement.

A) is your answer for:

Side with measurement 1 (30°): 5

5 is your measurement for the side measurement of 1. The next measurement (60°) must be x √3: 5 x √3 = 5√3 (Side on the bottom).

The last measurement (90°) 2 is twice the measurement of 1: 5 x 2 = 10 (Hypotenuse, side on top).

A) is your answer.
