Question

two vertices of a triangel are (3,2), (-2,1) and its centroid is [5by 3, -1 by 3 ] find the third vertex​

Answer 1

Answer:

(4,-4)

Step-by-step explanation:

Let

A = (3,2)

B = (-2,1)

C = (x,y)

centroid = (5/3,-1/3)

Formula of Centroid =

{ x1+ x2+ x3 /3 , y1+ y2+ y3 /3}

hence,

[ (3) + (-2) + x = 5 ] and [ (2) + (1) + y = (-1) ]

SOLVING THESE TWO WE CAN GET THE VALUES OF X AND Y.
