@Directrix I'm sorry I thought I understood what I was doing but if you could just explain how to solve for w please, and @Zelda if you can help i would appreciate it

First, you have to know what the 306090 theorem says. It is written above in both symbols and words. Next, you have to know the names of the parts of the 306090 triangle. I am marking them on a drawing. dw:1360705600824:dw

Do you understand that so far?

We will go step by step so that you understand. That is why I am asking.

If one angle of a right triangle is 30, then the other acute angle is 60. So, we have a 60 leg. Then, there is the hypotenuse. dw:1360705782032:dw

Does that make sense? If so, we're about to break out the theorem. :)

That's good news. So far, so good.

We want the length of w which is the hypotenuse. But, all we are given is the 60 leg.

When fooling with the 306090 theorem, get the 30leg first. I know we are not asked for the 30leg but the 30leg is the key to finding w, the hypotenuse.

Theorem Time; The 60leg is sqrt(3) times the 30leg. Agree?

Note that in the latest posted picture, the 60 leg shows up as sqrt(3) times the 30leg.

Yes, I am aware of that.

The second part of the 306090 theorem states that the hypotenuse is two times the 30leg.

You can see the pattern in the diagram. That was what Zelda was talking about.
