Best ResponseYou've already chosen the best response.0\[\rm sin \rm \theta = \frac{ opposite }{ hypotenuse }~~~~ \cos \theta = \frac{ adjacent }{ hypotenuse } ~~\tan \theta = \frac{ opposite }{ adjacent }\] which one you should use ? to find x you should know one angle and one side

Best ResponseYou've already chosen the best response.0so you have to use sin 40

Best ResponseYou've already chosen the best response.0it's okay why we have to use sin ? bec they gave you opposite side of angle now you know one angle and one side so you can find hyp \[\huge\rm sin 40= \frac{ opposite }{ hyp }\] solve^ sin 40 degree

Best ResponseYou've already chosen the best response.0ohh alright then you have to use unit circle sin value is what at 45 angle remember in order pair x coordinate represent cosine and y coordinate represent sin
