Have you drawn the forces diagram and resolved forces?

So where is the rope tension and friction on the diagram?
The key thing is to put all forces on the diagram to create the force equations.

I don't know where to draw the rope tension as in the angle I can't visually understand it

It's at 25 degrees to (above) the slope. Imagine youre dragging a sledge by a rope up a hill. This is similar.

25 degrees to the slope, so ... to the horizontal.
Generally you'd put the rope at the leading edge of the block, but not too important.
Where is the friction?

Friction has an arrow (direction) which isn't on your diagram. You must have covered an example/question like this?

your 25 degrees is in the wrong place. it should be between the slope and the rope.

Leading edge of the box. It is not too important (convention) where it is, but angle and friction are important.
