Yo guys i really need your help on this one part iii Q9

Now why is Vice City on your Task Bar Supposed to be exam time

Anyway.. the midpoint of AC is equal to the midpoint of DB, as diagonals bisect each other.
I think you can figure out the rest.

'Give non-exact numerical answers correct to 3 significant figures, or 1 decimal place in the case of angles in
degrees, unless a different level of accuracy is specified in the question.'

It's written on the front of every paper =)

Q6 (i). tan3x = ktanx where k is a constant and tanx ≠0.
By first expanding tan(2x + x), show that (3k-1)tan^2(x) = k-3
It's simple trigonometry, I know, but I can not come up with the expression they've given :/
