Find the three components of the resultant of the two forces

Find the three components of the resultant of the two forces acting at A acting. Points B and C are in the xz plane. Answer(s): 400 400° 765lb 40° 15° 30° 25°

Solution

x component = 765*sin(15)cos(25) - 400*sin(40)cos(60)=50.9lb

z component = 765*sin(15)sin(25) + 400*sin(40)sin(60)=306.3lb

y component = -765*cos(15) - 400*cos(40)=1045.4lb

the closest answer is A.
