Replace the force system acting on the frame by an equivalent resultant force, and specify where the resultant's line of action intersects member AB(Figure 1). Suppose that F1 = 30 lb, F2 = 50 lb, and F3 = 60 lb.

-Determine the magnitude of the resultant force. Express your answer in pounds to three significant figures

-Determine the angle between the resultant force and the x axis. Express your answer in degrees to three significant figures

-Specify where the resultant's line of action intersects member AB, measured from point A .Express your answer in feet to three significant figures.
