Two forces of 50 and 70 N (newtons) act on an object. The angle between the forces is 40°. Find the magnitude of the resultant and the angle that it makes with the smaller force.

Draw the diagram. Establish an x axis along the direction of the 50N force. break the other force in to x, y componsnts. Add the forces as vectors in x,y directions.
Then use your trig to find the resultant. I will be happy to critique your work.
