For the,
1. One had to use the formula T.S.A, which had 'h' in there. Then you had to find 'h' by the Volume and then solve.. It was F****** easy.
2. The answer to this question was R(7,15), maybe, don't remember pretty well... All one had to do was find the point of intersection of the imaginary perpendicular line. Then add up using the vector rule. I have uploaded a file for this question, it is just imaginary (Not to scale).
3. One gets two values one is '2' and the other is '-2'. Then you might as well get two answers for 'k'. Which would find you the second answer.

P.S My paper was held past 24 hoursNot to scale.png
