HeArty: it's B
HeArty: cosec©=√10
cutiepie9054: yes it is B
HeArty: we know that Sin©=1/cosec©..so sin©=1/√10.......i have a formula sin^2©+cos^2©=1...\\=>cos^2©=1-sin^2©......put the value of sin© in this eq.......we get.//// cos^2©=1-1/10/////cos^2©=9/10.../////cos©=3/√10.......//// By formula cos©=1/sec©\\\\\. sec©=√10/3
