Student, draw a CROSS-SECTIONAL diagram. That is, a circle and a line intersecting it; label parts that depict r=13 and distance from center to intersecting line. Look! there's a right triangle there. You should be able to complete your task.
Remember, in Geometry one picture is worth 1,000 words.
If Mark won't take those 3 points, I will!
