3. Two forces, F a and F b , are acting on a particle as shown. Let F a = 110.0 lb and β = 40.0 degrees. Find the magnitude and orientation angle θ of F b so that the resultant force R is acting along the dashed line r-r as shown and has the magnitude of 90.0 lb. Assume that F a is always horizontal.
