The distance between the circumcenter and the orthocenter of the triangle is approximately 19.8 feet.
The distance between two points in a coordinate plane can be found using the distance formula:
Distance = √((x2 - x1)² + (y2 - y1)²)
Using the given coordinates (-6, 6) and (8, -8), the distance between the circumcenter (Trina) and the orthocenter (Mark) can be calculated as:
Distance = √((-6 - 8)² + (6 - -8)²) = √((-14)² + (14)²) = √(196 + 196) = √392 ≈ 19.8 feet
