Question

In triangle ABC,G(-4,-7) is the centroid.IfA(-14,-19) andB(3,5) then find the coordinates of c​

Answer 1

Answer:

by using formula of centroid..

• a ,b,c are the points and g is the centroid.
• x1 +x2+x3 \3=-4(value of x in point g.)
• -14+3+x3=-12
• -11+x3=12
• x3=-1

y1+y2+y3\3=-7(value y in point g.)

• -19+5+y3=-7×3
• -14+y3= -21
• y3= -7
• so pint c (-1,-7)
