Best ResponseYou've already chosen the best response.1right you need to know these definition of sin, cos , and tan \[\rm sin \rm \theta = \frac{ opposite }{ hypotenuse }~~~~ \cos \theta = \frac{ adjacent }{ hypotenuse } ~~\tan \theta = \frac{ opposite }{ adjacent }\] dw:1439524382597:dw so sin = ??

Best ResponseYou've already chosen the best response.1yes right but you can't leave the radical sign at the denominator so multiply denominator and numerator by sqrt{74}

Best ResponseYou've already chosen the best response.1\[\huge\rm \frac{ 5 }{ \sqrt{74} } \times \frac{ \sqrt{74} }{ \sqrt{74} }\] what did you get ?

Best ResponseYou've already chosen the best response.1\[\huge\rm \frac{ 5 }{ \sqrt{74} } \times \frac{ \sqrt{74} }{ \sqrt{74} }\] now we don't need decimal answer \[\frac{ 5\sqrt{74} }{ 74 }\]
