Best ResponseYou've already chosen the best response.3some helpful hints that you'll need to use: \[\sec 20 = \frac{ 1 }{ \cos20 }\] You'll probably also need to use this one: \[\sin2x = 2sinxcosx \rightarrow 2\sin2x = 4sinxcosx\] Lastly, recall that you'll be using exact values here so you'll need this: dw:1436160583596:dw
