    You cannot, since it is not a right triangle

    if DF is a diameter then it is aright angled triangle.

    as @surjithayer said, that is, Thales' theorem -> http://www.mathopenref.com/thalestheorem.html

    so.. since it's a right triangle knock yourself out with the "pyghatorean theorem" :)

    |dw:1437179218568:dw| \(\bf \textit{pythagorean theorem}=c^2=a^2+b^2\implies c^2-b^2=a^2\\ \quad \\\implies \sqrt{c^2-b^2}=a \\ \quad \\ \qquad \begin{cases} c=65\\ b=60 \end{cases}\implies \sqrt{65^2-60^2}=a\)

    \[\sqrt{65^2-60^2}=\sqrt{\left( 65-60 \right)\left( 65+60 \right)}=\sqrt{5*125}=\sqrt{5*5*25}=25\]
