Question

In triangle TUV, Y is the centroid. If YW=30, what is TY?

Answer 1

TY=15 because the points bisect each other

Answer 2

TY = 60

D is correct

Explanation:

In triangle TUV, Y is the centroid.

As we know the centroid of the triangle is divides median into 1:2 ratio. The ratio is length of median from centroid to the side to length of median to opposite vertex.

Therefore, WY:TY = 1:2

`(WY)/(TY)=(1)/(2)`

where, WY=30

`(30)/(TY)=(1)/(2)`

`TY=2* 30`

`TY=60`

Hence, The length of TY is 60
