Need help with Special Right Triangles

[LlamaParty]

Okay so, I need help with a few of these problems. I get the basic idea of what I need to do for these problems, but some of them that involve fractions are giving me trouble because i have no idea how to work the fractions- All of the problems below that have fractions are the ones i need help on-

My goodness. You are given the formulas. It is pure plug and chug.

The first problem has no fractions in it. How did you do that one?

The second has no fractions in it. How did you do that one?

I agree with JeffM--My goodness.

30-60-90: For the ones which you are given x, to get the next column multiply by sqrt(3). To get the last column multiply x by 2.

If you are given xsqrt(3), then divide by sqrt(3) to get x. Once you have x, just multiply by 2 to get 2x.

If you are given 2x, then divide by 2 to get x. Now multiply x by sqrt(3) to get xsqrt(3).

Post back with your work.
