Show how did the theta have been solved from the two equations and Fcd?

Equations of Equilibrium. Referring to Fig. a, +EF = 0; NA - 200 cos 0 = 0 +/F = 0; FCD +0.25(200 cos ) - 200 sin 0 = 0 Also, by referring to Fig. b, +ΣFy = 0; NB - 150 cos 0 = 0 +/EF = 0; 0.35(150 cos 0) FCD - 150 sin 0 = 0 Solving Eqs. (1) and (2), yields - 0 = 16.3° ΝΑ = 200 cos 0 FCD= 8.23 lb NB = 150 cos 0
