What is 4x+56y=100 divide it by 200
resultant force will act on 65° n of w.
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.
