The pelvis \( P \) is connected to the femur \( F \) at \( A \) using three different muscles, which exert the forces on the femur as shown on the (Eigure 1) \( F_{1}=50 \mathrm{~N} \) Determine the magnitude of the resultant force. Express your answer to three significant figures and include the appropriate units. Part B Determine the resultant force orientation \( \theta_{R} \) as an angle measured counterclockwise from the positive \( x \) axis Express your answer in degrees to three significant figures.
