In the diagram, $\overline{AC}$ is a radius of circle A. Is $\overline{CB}$ tangent to circle A? Explain.

$\overline{CB}$ is not a tangent because $13^2+27^2\ne30^2$
$\overline{CB}$ is a tangent because $13^2+27^2\approx30^2$
$\overline{CB}$ is a tangent because $13^2+27^2=30^2$
$\overline{CB}$ is not a tangent because $13^2+27^2=30^2$
