Question

In a 30 degree - 60 degree - 90 degree right triangle find the value of x

A.5
B. 20
c. 5 over the square root of 3
D. 5 over the square root of 2

Answer 1

The correct answer is c) 5√3

Explanation:

In order to find this, we start by using the 30-60-90 proportions (1 - √3 - 2). Now, we use the side with 10 and the side with x to create a proportion.

x/10 = √3/2

Now cross multiply to solve for x

2* x = 10 * √3

x = 5√3
