Resolving for N, you take F from the ground and then the resultant forces, but Nsin35 isn’t the horizontal component...
N has a horizontal component so draw a right angled triangle (one vertex is P) to resolve things as usual. They've already given you an angle and two of the sides.
Sorry, I still can’t see it. I was under the impression that resolving horizontally had to go in the opposite direction and vice versa to vertically. I’m very confused, I see what you mean by Nsin35 right angle triangle but not sure why they would be equal or rather why it’s took as a horizontal component
Why not draw your own diagram, concentrating on the horizontal forces and upload it together with the force equation that describes horizontal equilibrium. It's easier to help if I can understand what you think.
It might help to draw a horizontal line through P so that you can see what the angles are. Since the ladder is at an angle 35 degrees to the ground, a horizontal line through P makes an angle 35 degrees with the ladder (alternate angles). Given that the force N is normal to the ladder at contact point P, you should now be able to resolve N into its horizontal and vertical components.
If you had a ladder, for example
Both forces are horizontal so you can equal them, so why isn’t Nsin35 horizontal but it equals force on the ground ?
You confused me because I got it last night, it’s because I drew the triangle wrong lmao
