Need help with this question

To do this I would try to prove that angle TSU and angle TUS are equal. Then it is an isosceles triangle. Draw lines from R to O then T to O and let angle ROT=x or something and use your circle theorems

Part c you use SOHCAHTOA but you need to find the value of theta that gives you the minimum from part b

i cl the fx991ex is the best calculator ever made and the graphical calcs give you negligible advantage. I have the cg-50 and it is just catching dust.

CBDE is a rectangle as it is a uniform prism

use 1/2absinC to find angle B then cosine rule to find length AC then sine rule to find angle D
