Question

A 30° – 60° – 90° triangle is shown below. Find the value of x.

Answer 1

Answer:

5

Step-by-step explanation:

In a 30-60-90 triangle, the side opposite the 30 degree angle (x) is equal to n, the side opposite the 60 degree angle (y) is equal to n$\sqrt{3}$, and the hypotenuse (10) is equal to 2n

knowing this, set 10 = 2n

n = 5

since we want to find x, the side opposite the 30 degree angle, this is equal to n = 5

x = 5
