The Attempt at a Solution
Part C is confusing me.
I got the height PQ to be 16/3root6
But I'm lost as to how to find the length SP. The mark scheme has the answer as 8, or (SP/2 = 4 therefore SP = 8) but I still can't figure it out, maybe it's 'cause I've been doing questions all day.
Can someone shed some light on this for me please.
