Member ABC is supported by a pin and bracket at $B$ and by an inextensible cord attached at A and C and passing over a frictionless pulley at D $.$ The tension may be assumed to be the same in portions $AD$ and $CD$ of the cord. For $P=105N$ and neglecting the size of the puliey determine:

A$.$ the tension in the cord, call it ada

B$.$ the reaction at $B,$ Gill it bbb

C$.$ the angle of the reaction at B w$.$r$.$t$.$ the x$-$axis, call it ccc
