Question

If the centroid of a triangle formed by points P(a,b) ,Q(b,c) and R(c,a) is at origin . What is the value of a+b+c=?

Answer 1

• ............. ......................

Answer 2

Answer:

0

Step-by-step explanation:

→the centroid formula of a triangle when there co ordinates are given that as (x1,y1),(x2,y2),(x3,y3) is given as

→ x = x1 + x2 +x3 , y = y1 + y2 + y3

3 3

→so as per given question the centroid is origin that means (x,y)≈(0,0)

if we substitute x1,x2,x3,y1,y2and y3

we get

a + b +c = 0

i hope u understood this solution
