Question

Yadi sinA=12/13, therefore tanA aur cosAKa maan geyat kare

Answer 1

sinA=12/13 that means p/h. so, we have to find base ..
now, base=√13^2-12^2
=√25
=base= 5
now,
tanA= p/b=12/5,and
cosA=5/13..

Hope this helps uhh..

Answer 2

sin square A+cos square A=1
144/169-1=cos square A
eqalize the denominator
shift the square root
get value for cosA
then tan A=sinA/cosA
get value of tanA
