The altitude of an equalateral triangle is 6√3 units long what is the length on one side of the triangle a. 12 b. 6 c. (7√3) / 2 d. 14√3

A. 12

Step-by-step explanation:

If we split an equalateral triangle down, it will become 2 30-60-90 triangles. Remember your 30-60-90 triangle rules.

6√3 = x√3, so x = 6

2 (6) (for hypotenuse) = 12

Since the hypotenuse is one side of the bigger triangle, we have our final answer of 12.
