Answer 2

Answer:

imagine you were the mass... sitting on a flat surface, you can feel the ground pushing up on your ... vertical equilibrium R=mg

sitting on an inclined plane= the same thing BUT you also feel like you should be sliding down the plane... hence the components involving your weight

your entire weight isnt acting perpendicular to the plane

you feeling like you may slide down the incline is represented by one component parallel to the incline...

the feeling i mentioned in the first line (vertical) is represented by another component NOT perpendicular NOR parallel to incline but purely vertical...

R is the force perpendicular to the incline pushing you (combination of the components)
