In a right triangle, angle $B = 52\degree$ and the side adjacent to $B$ measures 15. To find the side opposite $B$ , which equation is correct?

$\\sin(52\degree) = \\dfrac{\\text{opposite}}{15}$

$\\cos(52\degree) = \\dfrac{\\text{opposite}}{15}$

$\\tan(52\degree) = \\dfrac{\\text{opposite}}{15}$

$\\tan(52\degree) = \\dfrac{15}{\\text{opposite}}$
