Question

यदि (9, a), (b, -4) व (7, 8) से बनने वाले त्रिभुज के केन्द्रक के निर्देशांक (6, 8) हैं तो
aव b के मान हैं​

Answer 1

Answer:

a=20 b=2

Step-by-step explanation:

Centroid = (x1 + x2 + x3 / 3 , y1 + y2 + y3 / 3)

According to question,

9 + b + 7 / 3 = 6

=> 16 + b = 18

=> b = 18 - 16

=>b = 2

a + (-4) + 8 / 3 = 8

=> a + 4 = 24

=> a = 24 - 4 = 20
