Here mass A will slide down and mass B will move above
Let the Tension in string be T and acceleration of system be a

For mass B
mBa = mBg*sin(37) - T
For mass A
mAa = T - mAg*sin(53)

So ,
mBg*sin(37) - mBa = mAa +  mAg*sin(53)


10×10×3/5 -10a = 2a + 2×10 ×4/5

60 - 10a = 2a + 16

a = 44/12 =3.67m/s2
