this took me ages, i kept trying to use vectors and graphs (y=mx+c)
turns out it was just a simple sine rule question
however i think i still got it wrong, i got 4.1489 degrees, which doesn't sound right. here is my working.

Alot of people at my school walk around solving these. its annoying, most of them think theyre so good because they can apply some algorithm they got off the net.
he will fail if he gets king twice in a row
prob of getting king once is 1/13
prob of getting king twice in a row is (1/13)2 = 1/169
thereforefore prob of not getting king twice in a row is 1- 1/169 = 168/169
but ccleaner only finds stuff it knows you dont need, like temp files. Overdisk shows you whats taking up all your space in the form of a pie chart so you can delete it, like stuff you forgot was ever there.
