In a Right Triangle, Find the Length of the Side $a=1 \mathrm{ft}, \mathrm{c}=23 \mathrm{ft}$

In a right triangle, find the length of the side not given. Let c represent the length of the hypotenuse. Give an answer to the nearest tenth if necessary.
- $a=1 \mathrm{ft}, \mathrm{c}=23 \mathrm{ft}$

A) $\mathrm{b} \approx 23.0 \mathrm{ft}$
B) $b=22 \mathrm{ft}$
C) $b \approx 24 \mathrm{ft}$
D) $\mathrm{b} \approx 4.7 \mathrm{ft}$
