ONE MORE METHOD TO SOLVE THE 33 SUM

use this in Mg - T = Ma
or M = T/(g - a) to get the answer....
T - nsin = M'a
=>T = M'a + nsin
=> T = M'a + (masin + mgcos).sin
= M'g.tan + mg.tan.sin2 + mg.cos.sin ..... using a = g.tan
= M'g.tan + mg (tan.sin2 + cos.sin)
= M'g.tan + mg (sin3/cos + cos.sin)
= M'g.tan + mg ( sin3 + cos2.sin ) / cos
= M'g.tan + mg (sin/cos).(sin2 + cos2)
= M'gtan + mg.tan
= (M'+m).g.tan

use this in Mg - T = Ma
or M = T/(g - a) to get the answer....
