Considering FBD

The equations involved are

N- reaction btw wedge and blk

N=.6gcos37 = .48g

For acc of wedge, Aw along incline
Nsin(53-37) + 1.2gsin53 = 1.2Aw

Aw = .91 g

Now acc of blk wrt wedge , Ab = gsin37 ? Awcos16 = -0.275 g

Net Horizontal acc, A = Absin53 + Awsin37 = 0.326 _~ .3251_~ 144/443 g

Note: The actual ans is approximated bcos of the various initial approx that I made in the sin and cos values . But the method of approach is same and genuine.
