3(c):

Heh, it looks like the marker wrote down 36 + 49, but didn't write the 9 properly and so read it as 36 + 42. The correct answer is d = sqrt(85).

2(c):

Your answer is correct. Not sure what they were thinking.

Yeah I noticed that today too... my teacher looked at them and said..."its not you, the answers a wrong". It's the best feeling you can get whilst doing a maths paper! :)
