## anonymous one year ago Anyone able to help me out with the 30-60-90 theorem? I'll post the question in the comments.

So I know how to do the 30-60-90 theorem. I know that it is the longer leg=$\sqrt{3}$ * shorter leg. But how do I find the hypotenuse?

3. beginnersmind

If you know the length of two sides you can find the third one using the Pythagorean theorem.

I believe the answer is 14, right? Because the hypotenuse cannot be shorter than the legs.

5. beginnersmind

That's correct and clever thinking as well.

Okay, thank you! After staring at it long enough, I was like, "Wait, it can't be any of these others because they're all the length of the leg or shorter!" Lol.

But if they didn't give you options you could use the fact that its an equilateral triangle cut in half. So if you know that the shorter leg is 7, the hypotenuse must be twice that.
