As shown in the figure, in the plane rectangular coordinate system, given the area of points a (- 5,0), B (3,0), △ ABC is 12, try to determine the coordinate characteristics of point C

As shown in the figure, in the plane rectangular coordinate system, given the area of points a (- 5,0), B (3,0), △ ABC is 12, try to determine the coordinate characteristics of point C

Let the height of △ ABC be h, ∵ point a (- 5,0), B (3,0), the area of △ ABC be 12, ∵ 12 × 8h = 12, the solution is h = 3, ∵ point C is on two straight lines parallel to the x-axis and the distance to the x-axis is 3
