Hi, this could quite possibly sound dumb, but never mind. I'm just working through some past papers with these type of questions, but my calculator doesn't allow me to set up the fractions as you do in the video. I've tried the alternative way, but it results in an error :S Where could I be going wrong or do you have any other tips? Thanks in advance.

I don't see how number 4 is 100.3 if the angle is smaller than a right angle. I know it's not drawn to scale, but surely they wouldn't confuse you by doing that.

@iLecter Hi, best to rely on the maths behind it rather than the "What it might look like" would be my tip.

do you need to remember that second formula for the exam?
CrazyChloe8 9 months ago in playlist maths revision
@CrazyChloe8 - You can use either. The standard one is in the formula book and can be transposed to give the other. Nice if you can remember the other but not essential to get the right answer
