We have, Cot theta = 9/40

Therefore, cosec theta = √ 1 + cot² theta

                                      = √ 1 + ( 9/40 )²

                                      = √ 1 + 81/1600

                                      =  √ 1681/1600

                                      = 41/40

Now, cot theta = 9/40

             tan theta   = 1/cot theta = 40/9

Therefore, sec theta = √ 1 + tan²theta

                                  =  sec theta = √1+ ( 40/9)²

                                 =  √ 1681/81

                                 

                    \implies \boxed{\mathsf{41/9}}
