Three horizontal forces act on a test platform. The east–west and north–south components of each force are recorded below.
| Force | East–west component | North–south component |
|---|---|---|
| A | 85 N east | 40 N north |
| B | 35 N west | 25 N south |
| C | 20 N west | 55 N north |
Calculate the east–west and north–south components of the force needed to put the platform in equilibrium.
