Solve X
How do you find out what X is?

Re: Solve X
I'm assuming this is a trigonometry problem. Use the law of cosines because this is not a right triangle (as far as I can tell. I can't read the degrees. Enlarging anyone?).

How should I use the cosinus law to calculate x?

Re: Solve X
Ack! I took another look and realized that the law of cosines doesn't work here.

Re: Solve X
The cosine law does not easily apply, but the law of sines does.
It then becomes a simultaneous equation.
