Question

8. The veetices of triangle are (1, 2) (3, 5)
and its centroid is orgin. find third vertex
​

Answer 1

Answer:

(-4,-7)

Step-by-step explanation:

• centroid formula =(X1 + X2 +X3 )/3. + (y1+ y2+y3)/3
• given verticed (1,2) X1 =1 and y1:= 2

other vertice X2 = 3 and y2= 5

and centroid given is origin that is x and y co ordinates are 0

now convert in formula

we get

1+3+X3/3= 0

1+3+X3 =0

4+X3=0

X3=0-4

X3 =-4

2+5+y3 \3=0

7+y3=0

y3=0-7 that implies-7 so X3=-4 and y3= -7
