Best ResponseYou've already chosen the best response.1Yes. csc= hypotenuse/opposite sec=hypotenuse/adjacent cot=adjacent/opposite

Best ResponseYou've already chosen the best response.0okay cool :) So from there, it is just trial and error as you see which of A,B,C or D is correct ^^

Best ResponseYou've already chosen the best response.1I'm kind of confused though, the csc options are 3/4 or 4/3 but where are they getting those numbers from?

Best ResponseYou've already chosen the best response.0There are gotten, by interpreting the diagram :) Here I'll explain how to get the correct one !

Best ResponseYou've already chosen the best response.1I just realized that 8 is the hypotenuse and half of 8 is 4, and the opposite is 6 and half of 6 is 3 :)

Best ResponseYou've already chosen the best response.0Ah okay, I'll help out ! Sine Rule for nonright angle triangles is SinA = SinB a b

Best ResponseYou've already chosen the best response.0By the way, do you sometimes forget your inverse trig ratios? Because I got a neat trick that you can't forget them :)

Best ResponseYou've already chosen the best response.1Yeah I do sometimes!

Best ResponseYou've already chosen the best response.0The trick is to remember every 'third' letter of the inverse function For example Se'c' = Cos Co's'ec = Sin Co't' = Tan
