So have you started this yet?

anonymous · Answer

Well I'll be honest with you, I don't know if it's how this is phrased or whatever. But I have no idea how to even being working this out. Anything you can say is probably help

hero · Answer

Basically, they want you use trigonometry to find a missing side. You already know that 

$$\sin(\theta) = \frac{opp}{hyp}$$$$\cos(\theta) = \frac{adj}{hyp}$$$$\tan(\theta) = \frac{opp}{adj}$$

You also know that $$a^2 + b^2 = c^2$$ and A + B + C = 180 you can use that to verify that the numbers are correct. 

So make up some values for angles A or B. Then make up a value for two of the sides of the triangle. Then use trigonometry to find the third side. Use the pythagorean theorem and the sum of angles of triangle formula to make sure that the numbers are consistent with the correct values for a right triangle.

It's too bad that the instructions weren't expressed more explicitly.

Make up a value? I don't understand. I don't mean to make you give me the answer or anything but can you like walk me through the first few steps or something. Sorry. :(
