Answer:

B. 7 m

Explanation:

The Pythagorean theorem states that
a^(2) +b^(2) =c^(2), where a and b are sides of a right angle, and c is the hypothenuse (the longest side).

Plugging our numbers in, we get
7^(2) +b^(2) =10^(2) ->
49 + b^2 = 100 ->
b^2 = 51.

since
7^(2) =49, b would be the closest to 7.
