In a 30-60-90 triangle, how many sides do you need to know in order to determine the remaining sides? 2013

Sagot :

Option (c)

Given:

The objective is to find the number of sides required to find the remaining sides in a 30-60-90 triangle.

Since, one of the angle is 90°, then it is a right angled triangle.

For a right angled triangle any one side of the triangle is enough to find the other two sides of the triangle using trigonometric ratios.

Hence, option (c) is the correct answer.
