Thanks for the question! For this one you’ll want to think about the total momentum for both the x and y components separately. The momentum will be conserved so taking the x components you will see
M1V1 = (M1+M2)Vcos(a)
For the y components you’ll get 
-M2V2 = -(M1+M2)Vsin(a)
(We use negatives because the mass is moving in the negative y direction)
Now using the Tangent rule we get 
tan(a) = M2V2/M1V1
So for your angle a
a = tan^-1(M2V2/M1V1)
