That's a special triangle. In the 30-60-90 triangle, the proportion of the sides are \(\ \sqrt{3}:1:2\), respectively.

How would I solve for the sides though?

That means the side lengths are ....?

7, 14, and 12?

Use the Law of Sines http://en.wikipedia.org/wiki/Law_of_sines

Ummm... Well, you have 7, and 14, so substitute 7 as x in the shortest side, and get 7sqrt3. So the answer is \(\ \huge 7, 14, 7\sqrt{3} \).

I thought that was 7*the sqrt of 3 lol

@robtobey I was going to suggest that at first; however, I think this method is equally as effective.

@ThaJokersRiddles Does this make sense to you now?

Yea

The problem statement does not infer a right triangle.

Great!

@robtobey, @ThaJokersRiddles drew the problem that indicates a right angle.

Ok. I stand corrected.

However, the law of sines would be effective had this been a non-right triangle.
