Question

I need help on this one thanks!!

Answer 1

CU = 12

Explanation:

Clearly from the diagram of the triangle we can say that,

AD, BE and CF are the medians of the triangle ABC , since they are bisecting the sides of the triangle equally.

Also , U is the intersection point of the these mediands of the triangle whic is known as centroid of the triangle.

Now, from the property of the centroid , centroid divides the median in the ratio of 2 :1 from the point C .

Thus CU will be
`(2)/(3)` times of CF (median) .

Given is Cf equals 18 ,

Thus , CU =
`(2)/(3)`×18 = 12.

So, CU equals 12 .
