+738 hi notsmart2.0!
firstly, we can find the length of the leg of the smaller right triangle.
\(1^2+x^2=5^2\)
\(1+x^2=25\)
\(x^2=24\)
\(x=\sqrt{24}\)
now, we can find the value of ? since we have both side lengths of the right triangle.
\((\sqrt{24})^2+5^2=?^2\)
\(24+25=?^2\)
\(49=?^2\)
\(\boxed{?=7}\)
i hope this helped you!
:)
