Select the correct answer. What is the value of y in the triangle?
y
30°
60°
6
O A.
3
OB. 6
C. 673
D.
33

This is a special kind of right triangle, called a 30-60-90 triangle.

Across from the 30 degree angle, the side is equal to x. Across from the 60 degree angle, the side is equal to x. And across from the 90 degree angle, the side is equal to 2x.

Using what we know about 30-60-90 triangles, lets first solve for x. We know that the hypotenuse, given, is equal to 6.

2x = 6

x = 3

Then, we are looking for the side opposite of the 60 degree angle. So its value is  x.

x = 3

3 *   = 3

y =  3 (option D)

Hope this helps!! :)
