8/17

17/7

1/17

7/17

Other:
​

Answer 1

Answer:

7/17

Step-by-step explanation:

8tan A = 15

tanA = 15/8

tanA = perpendicular/base

so,

perpendicular = 15

base = 8

by pythagoras theorem,

we find hypotenuse that is 17

sinA = perpendicular/hypotenuse = 15/17

cosA = base/hypotenuse = 8/17

sinA - cosA = 15/17 - 8/17

=>7/17
