Means we should take tension or compressed force only sir

Sir in problem 5 we taken sin in x direction and cos in y direction
But in problem 7 we taken cos in x direction and sin in y direction .
Why we should consider like this?

sir,
same problem if the blocks are connected by a rope and mention some angle as 45.Then how can we will do this problem.We must know the value of coefficient of friction.

[yakkaliharshitha]

Sir,
How we can know to take 's' and 'p' values

Sir, sometimes on y-axis taking cos tita and sometimes taking sin tita give me clarity sir, ,
