If the plane $7x + 11y + 13 z = 3003$ meets the axes in A, B and C, then the centroid of ΔABC, is |
(143, 91, 77) (143, 77, 91) (91, 143, 77) (143, 66, 91) |
(143, 91, 77) |
Given plane meets the coordinates axes at A(429, 0, 0), B(0, 273, 0) and C(0, 0, 231). So, the coordinates of the centroid of ΔABC are $\left(\frac{429}{3}, \frac{273}{3}, \frac{231}{3}\right) $ i.e. (143, 91, 77). |
