$tan(A)=3/4$

$5sin(A)=3$
$sin(A)=3/5="opposite side"/"hypotenuse"$

$"hypotenuse"^2 = "opposite side"^2 + "adjacent side"^2$

$5^2=3^2 + "adjacent side"^2$

$:. "adjacent side"=sqrt(5^2-3^2)$

$"adjacent side"= 4$

$tan(A)= "opposite side"/"adjacent side"=3/4$

If 5*sinA = 35*sinA = 3 , then what is the value of tanAtanA?
