Heya,

tan A= 15/8=perpendicular/base

sinA=perpendicular/hypotenuse

cosA=Base/hypotenuse

By Pythagoras theorem:-

(H)²=(P)²+(B)²

(H)²=(15)²+(8)²

(H)²=225+64

(H)²=289

H=17

sinA=15/17

cosA=8/17
                     
Therefore,
sinA-cosA
=15/17-8/17
=15-8/17
= 7/17 ANSWER..

HOPE IT HELPS:-))
