Answer:
Resultant force will act on 65° N of W.
Step-by-step explanation:
As given in the question one bulldozer exerts force of 1250 pounds in western direction and 2650 pounds in northern direction and we have to find angle A which is an angle between 1250 pounds of force and resultant force F.
Therefore tan A= Force on North direction/ Force on west direction = 2650/1250 = 2.12
⇒
A = 64.75
A = 65° North of west.
