Answer 2

Answer:

131/60

Step-by-step explanation:

Given, 13 sinA = 12

=>  sinA = 12/13  (ie., opp/hyp )

=>  adj = $\sqrt{hyp^{2} - opp^{2} }$

            = $\sqrt{13^2 - 12^2 }$

            = $\sqrt{169-144}$

             = √25

    adj    = 5

=> secA = hyp/adj = 13/5

 & tanA = adj/opp = 5/12

=> secA - tanA = 13/5 - 5/12  = (13*12 - 5*5 )/60

                                              = (156-25)/60

                                              = 131/60
