Ok final one. I think, possibly I know how to do this.

Ok question goes sorta like this [summarized]

An incline that transports passengers back and forth [up and down] a mountain, has an angle elevation of 30 degrees. Angle of elevation to the top of the track from a point horizontal 100 ft from the base which is about 26.8 degrees. What is the lengh of the track?

Uhm, too lazy to draw the pretty triangle lol.

On this problem do i just do 180-30-26.8= 123.2

and carrry it on out by uaing the law of sines ( a / sinblah = b / sinblah )?
