1. The problem statement, all variables and given/known data

Find the work W done by the 15-newton force.

2. Relevant equations

W=\vec F\cdot\vec s=\left|\vec F\right|\left|\vec s\right|\cos \theta

3. The attempt at a solution

W= 15*cos140*160 = -1838.506

I don't know why mastering physics was telling me "Not quite. Check through your calculations; you may have made a rounding error or used the wrong number of significant figures."
