Maths A-Level Mechanics

Hii, I am hoping somebody who enjoys moments could do this question for me as I would appreciate thorough annotations on the diagram to help me understand. I am convinced I have dyslexia and struggle to visualise things.
Thank you so much in advance )

You should be able to draw the rod weight acting at the com/midpoint and also the normal reaction to the wall at B? Then its just a case of equating the two moments using simple trig? Which part are you stuck with?

I'm not confident in drawing diagrams

When It says anything about a smooth wall, it says that there is a support force perpendicular to the wall acting away from it.
When it says rough floor there is a horizontal force opposing the horizontal force on the rod
Also when you have a non vertical or non horizontal force, you can resolve it along horizontal and vertical lines by using a triangle.
If you seriously hate moments, you can also try to solve this using forces directly and make a resultant force about vertical and about horizontal (although the way the question is structured, you would get the value of the answer in B before A if you do this).

It will improve with practice. So try drawing two of the forces acting on the rod. So gravity/weight at the com and the normal reaction at B and upload a pic?
