Question
If you are given the SHORT LEG of a 30-60-90 triangle, select the way to find the LONG LEG?
- Multiply by 2
- Divide by 2
- Multiply by
- Divide by
Hint:
The given question is about a right-angled triangle. It is a 30°-60°-90° triangle. The triangle has two legs. One is longer than the other. And the third side is the hypotenuse. We are asked to tell a way to find the longer leg, when it’s shorter leg is given . We will use the properties of a 30°-60°-90° triangle to find the answer.
The correct answer is: Multiply by
It is 30°-60°-90° triangle.
We will use the properties of this triangle to find the answer.
In a 30°-60°-90° triangle, the length of hypotenuse is two times the length of the smallest side. It’s longer side is √3 times the value of the smallest side.
To find the longer side, we will multiply the shorter leg by √3.
The right answer is “ multiply by √3”.
For such questions, we should know the properties of different triangles.
