Hii friend,

8 Tan A = 15

Tan A = 15/8 = P/B

P = 15 and B = 8

By pythagoras theroem,

(H)² = (P)² + (B)²

(H)² = (15)² + (8)²

(H)² = 225+64

(H)² => 289

H => ✓289 = 17


Therefore,


Sin A = P/H => 15/17

And,

CosA = B/H => 8/17

SinA - CosA

=> 15/17 - 8/17

=> 15-8/17 => 7/17


HOPE IT WILL HELP YOU.... :-)
