Question

the centroid of a traingle is the point(6, -1). if 2 vertices are (3, 4) and (-2, 5) find the third vertices​

Answer 1

Answer:

x1 + x2 + x3/3 is the x coordinate of centroid

y1 + y2 + y3/3 is the y coordinate of centroid

3+(-2) + x/3 = 6

x+1=18

x=17

and 4+5+y/3 = -1

9+y=-3

y=-12

third vetice will be (17,-12)
