An object of mass M = 1,338 g is pushed at a constant speed up a frictionless inclined surface which forms an angle θ = 50 degrees with the horizontal. Incline is increasing. What is the magnitude of the force that is exerted by the inclined surface on the object?

Again, what is the normal force of weight?
Tilt your axis such that, Y is pointing to the opposite of Weight of M. And X is pointing towards the right. (like usual). [The axis shown in the diagram requires you to find Fnet, which I don't know how to find; thus use this method].
In that case,
Positive being up,
-W(of M)+Ncos50=0
=> N=Mg/cos50
plug your numbers, that's your answer.
