$D.\:8.7$

1) Assuming this is a right triangle, we can find the missing leg by making use of the Pythagorean Theorem.

2) Thus, we can write out this:

$\begin{gathered} c^2=a^2+b^2 \\ \\ (10)^2=5^2+b^2 \\ \\ 100=25+b^2 \\ \\ b^2=100-25 \\ \\ b=√(75) \\ \\ b\approx8.7 \end{gathered}$

Note that the hypotenuse (the largest side) is always on the left side. And that this is an approximation rounded off to the nearest tenth.

3) Thus, the answer is:

$D.\:8.7$
