Answer:
A)
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.
