Cool. Awesome.

My sister said that for these questions, they didn't typically need the double angle..I guess she didn't know what to do when the 2 was in front of the cos.

Just make sure that when you have something like you always apply double angle formula, and dont include the 2 in your working out for x until the end, this was a mistake I made, which TT helped me with.
