Answer 1

Hope it helps :) look for the given and solve

Answer 2

Answer:

1/9

Step-by-step explanation:

Given:  3x = sec theta and 3/x = tan theta

Proof: sec^2 theta = (3x)^2 = 9x^2                    

          tan^2 theta = (3/x)^2 = 9/x^2                  

           We know that,

                                     sec^2 theta - tan^2 theta = 1

                                                          9x^2 - 9/x^2 = 1

                                                      9 ( x^2 - 1/x^2 ) = 1

                                                         ( x^2 - 1/x^2 ) = 1/9
