Question

If A(a,5) B(-1,-6) C(-4,b) are the three vertices of triangle ABC and centroid is (-1/3,2) Then find (a+b),

PLEASE DO CORRECTLY
IF U DO CORRECTLY MEANS I WILL MARK HAS BRAINIEST ANSWER​

Answer 1

Answer:

a=4

b=7

Step-by-step explanation:

G1= A1+B1+C1/3

-1/3=a-1-4/3

-3=3(a-5)

-3=3a-15

3a = 15-3

3a= 12

a=4

Now, G2= A2+B2+C2

2 = 5-6+b/3

2×3= -1+b

6= -1+b

b= 6+1

b=7

Answer 2

Answer:

Step-by-step explanation:

X CORDINATES=

x1=a

x2=-1

x3=-4

Y CORDINATE=

y1=5

y2=-6

y3=b

Xcordinate of cntroid=x1+x2+x3/3

-1/3=a-1-4/3

a=4

Ycordinate of centroid=y1+y2+y3/3

2=5-6+b/3

b=7

a+b=4+7

     =11
