4. An architect designs a triangular jogging track around a circular pond. Each side of the track just touches the pond. The circle is inscribed in the triangle. The center of the circle is called the incenter of the triangle. The diameter of the circle has length 41. DA = 8x + 2z –1-, DB= 6x + y+ 1, DC = 11y-2z + 2. 2 Find x, y, and z.
