Dear Mentors/PF helpers,
Please help me with part (ii), I couldn't find a way through this part.
The Attempt at a Solution
(i) angle RPS = 65 deg (angles in the same segment are equal)
(iii) angle PRS = 110 - 65 = 45 ( exterior angle of triangle PSR equal two interior angles)
angle PQS = angle PRS = 45 (angles in the same segment are equal)
