A triangle with sides measuring 8, 15 and 17 units is inscribed in a circle. What is the radius of the circle, in units? Express your answer as a decimal to the nearest tenth.
It is a right triangle which means that the hypotenuse is the diameter of the circle. Therefore, the radius is 17/2=8.5 units.

Hello Guest!
The triangle with side lengths 8, 15, and 17 is a right triangle. In the x-y coordinate system, 8 is on the abscissa axis and 15 is on the ordinate axis.
Then:
\(r^2=(\frac{x}{2})^2+(\frac{y}{2})^2= (\frac{8}{2})^2+(\frac{15}{2})^2\\ r=\sqrt{ (\frac{8}{2})^2+(\frac{15}{2})^2}\)
\(r=8.5\ units\)
I came too late to the solution before my (Thales Circle).
