Can you help me solve this please :/

Answer:

2√3

Step-by-step explanation:

In a special right triangle called the 30-60-90 triangle, the ratios of the side lengths are x-x√3- 2x respectively. This means that the side opposite to the 60 degrees is x√3 and the side opposite to the 30 degrees is x.

Since the side opposite to the 60 degrees is 6, x√3=6

x√3=6

x=6/√3

rationalize the denominator:

6√3/3

simlify

2√3

so the answer is the third one. 2√3
