Hey, WOW, such amazing hand writing. Ikr?
If you can't see anything that i wrote (i'm sorry), try drawing a straight line down from point O to point R, it forms an isos. triangle, then make use of the tang. perpendicular to radius theory or concept (wtv it's called), giving you that 90°.
Everything else becomes easier after the first step. Try drawing next time ;) look out for tangents to the circle and the centre of the circle, helps a lot.
Have fun doing maths, bud : )

Welcome :)
Do u mind teaching me why the other tutor’s part (iii) final answer is different from yours?☹️
Hi nancy, the other tutor was finding reflex angle POT, i was trying to find the obtuse angle. I hope this helps :) revise our working and understand what we're trying to find and how we found them. Enjoy maths! ^_^
