A right triangle has a side length that measures 4 m and a hypotenuse that measures 8.5 m. What is the measure of the other side of the triangle?

Let the measure of the other side of the triangle be $x$. By the Pythagorean Theorem, we have $x^2+4^2=8.5^2$. Simplifying the equation gives $x^2+16=72.25$. Subtracting 16 from both sides gives $x^2=56.25$. Taking the square root of both sides gives $x=7.5$. Therefore, the measure of the other side of the triangle is $\boxed{7.5 \text{ m}}$.
