Find the length of the third side of the right triangle. Assume that $c$ represents the length of the hypotenuse. Give an exact answer and, if appropriate, an approximation to three decimal places.
-$a=1, b=9$
A) $\mathrm{c}=\sqrt{10} ; \mathrm{c} \approx 3.162$
B) $\mathrm{c}=\sqrt{80} ; \mathrm{c} \approx 8.944$
C) $\mathrm{c}=\sqrt{82} ; \mathrm{c} \approx 9.055$
D) $\mathrm{C}=10$

Using the Pythagorean theorem $c = \sqrt{a^2 + b^2}$, we find $c = \sqrt{1^2 + 9^2} = \sqrt{82}$, which approximates to 9.055.
