Question

the co-ordinates of vertex A of ∆ABC are (-4,2) and a point D which is mid point of BC are (2,5). The co-ordinates of centroid of ∆ABC are.​

Answer 1

Answer:

so... the coordinates of bc(2,8)

idk what centeroid is

Step-by-step explanation:

for x. coordinate

-4+x

------ =2

2

cross multiply

4=-4+x

x=4+4

x=8

for. Y coordinate

2+x

----- =5

2

cross multiply

10=2+x

x=10-2

x=8
