Dis the centroid of △abc . what is the value of x when bd=2x+30 and bf=6x ?

The calculated value of x, using the information given is 15 units.

From the diagram given :

BD = BF

Equate the expressions thus:

2x + 30 = 2/3(6x)

2x + 30 = 4x

Collect like terms

2x - 4x = - 30

-2x = - 30

Divide both sides by - 2

x = 15

Hence, x = 15 units
