gayaneshka [121]

Use Pythagorean's Theorem to solve for the missing leg length.

32^2-18^2=a^2

with a being the length of the missing leg. Simplifying we have

1024-324=a^2

and

a^2=700. If we are told to express our answer to the nearest tenth of an inch, then we are simply plugging that into our calculator to get 26.45 or, rounded correctly, 26.5
