Step-by-step explanation:

17 cos A = 8

cos A= 8/17

secA= 17/8

again,

cosA= 8/17

√1-sin²A= 8/17

1-sin²A= (8/17)²

1-sin²A= 64/289

sin²A= 1-64/289

sin²A= 225/289

sin²A= (15/17)²

sinA= 15/17

cosecA=17/15

hence cosecA=17/15 and secA=17/8

15cosec A - 8 sec A

15•17/15 - 8•17/8

17-17

Step-by-step explanation:

cosA = 8/17

H^2 = B^2+P^2

17^2 = 8^2+ P^2

289 = 64+ P^2

289-64=P^2

225=p^2

√225=P

15=P

15×17/15-8×17/8

17-17=0
