Considering block A and B and in between rope as a system. We can say that 

Along the direction of wedge, the component of gravitational force = actual gravitational force *sin (alpha)

= (Ma+Mb)*g*sin(alpha) = (14+12)*9.8*sin(19 degree) = 82.94 N

Now along wedge inclined plane only tension between Block A and wall is balancing this force

Hence Tension in wire that connects with wall = 82.94 N
