Question

in triangle abc a is equal to 58 D is the midpoint of BC and BD is equal to 2, - 1 find the centroid of triangle ABC​

Answer 1

Step-by-step explanation:

Given in triangle abc a is equal to (5,8) D is the midpoint of BC and BD is equal to 2, - 1 find the centroid of triangle ABC

• The  centroid divides the median in the ratio 2 : 1
• So we have A (5,8) and D (2, - 1) and m1: m2 = 2: 1
• So (m1x2 + m2x1 / m1 + m2 , m1y2 + m2y1 / m1 + m2)
•    (2(2) + 1(5)) / 2 + 1 , 2(-1) + 1(8) / 2 + 1)
•       (4 + 5 / 3, - 2 + 8 / 3)
•         (9 / 3 , 6 / 3)
•      = (3,2)
