Answer:

1) 9/17

2) 25/17 or 1  8/17

Step-by-step explanation:

assuming the value as x,

cot A =8x/15x

     |\                                                                              pythogarus theorem

     |   \     17x                                                                       225

15x|      \                                                                             +064

     |____\                                                                           289

         8x                                                                      = 17^2

1)1-cos A

1-8/17

=17-8

   17

=9/17

2)1+cos A

1+8/17

=17+8

   17

=25/17.
