Explanation / Answer

In Y-axis direction

component of vector A = 0

component of vector B = Bsin31

component of vector A = -16sin42

sum =0

so Bsin31 = 16sin42

B = 20.7569

along X-axis:

component of vector A = -A

component of vector A = 20.7569*cos31

component of vector A = 16cos42

sum =0

A = 20.7569*cos31+ 16cos42 = 29.68245
