Tan A= 15/8=perpendicular/base
sinA=perpendicular/hypotenuse
cosA=Base/hypotenuse

(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
                       sinA-cosA=15/17-8/17
                                         15-8/17
                                        → 7/17

SinA=15/17,CosA=8/17 (SinA-CosA)=(15/17)-(8/17) . =15-8/17 . =7/17
