In the diagram, is \overline{CB} tangent to circle A? Explain.

• \overline{CB} is not a tangent because \(13^2+27^2\ne30^2\)

• \(13^2+27^2\approx30^2\) is a tangent because \(13^2+27^2\approx30^2\)

• \(null\) is a tangent because \(13^2+27^2=30^2\)

• \(null\) is not a tangent because \(13^2+27^2=30^2\)
