Question

find the centroid of the triangle ABC whose vertics are A (2,5) B (-3,2) and C (7,-1)

Answer 1

Answer:

Step-by-step explanation:

→A(3,-2)

x1=3

y1=-2

→B(5,1)

x2=5

y2=1

→C(-4,1)

x3=-4

y3=1

x=x1+x2+x3÷3

x=3+5+(-4)÷3

→x=4/3

y=y1+y2+y3÷3

y=-2+1+(-1)÷3

→y=-2/3

→Centroid is (x,y)=(4/3,-2/3)
