How did you get 330.3m? I used the cosine law to get 1175.2m for the "missing" side.
With your numbers:
The question reads:
Due to previous tunneling experience, the firm estimates a cost of $18,000 per meter for boring through this type of rock and constructing the tunnel according to required specifications. If management insists on a 30% profit, what will be their minimum bid to the nearest thousand.
The sides are 1200m, 1600m, 330.3m
Attached is the picture of the triangle that I worked out.

If someone can explain how to continue on from here that would be fantastic.
I had to use the cosine law to get the 330.3m, so I thought it would be relevant to post here.

Good catch, I didn't enter the numbers in proper order and got the wrong answer. When I put them in all at the same time it came out to be 1175.2
So, continuing on with the triangle and the 30% profit, any tips?
