Here is how to solve this. Decide on a direction for each vector. Use your scientific calculator to do a polar-to-rectangular conversion - i.e., separate each vector in horizontal and vertical components. (Check your calculator's manual on how to carry out a polar-to-rectangular conversion.) Add the vectors by components. Finally, convert back to polar (rectangular-to-polar conversion, on your scientific calculator).
200 + n = 100 + 200200 + n = 300n = 300 - 200n = 100
F = M AM = F/A = 200/5 = 40 kg
One scale is reading 200N and the other is reading 400N.
400 N 400 N / 10cm2 = 2000 N / 50cm2
A force of 200*sqrt(2) = 282.8427N (to 4 dp) acting at 45 degrees to the two original forces.

arc tan -1.6 ≈ -57.99 + 180n degrees ≈ -1.01 + nπ radians ≈ -64.44 + 200n gradians.

Work = Force * Distance Force = 200N (gravity already taken into account because of N) Distance =1.5m Work = 200N * 1.5m Work = 300N*m = 300 Joules
About 45 pounds per 200N.
