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

Answer:

TY = 60

D is correct

Step-by-step 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

$\dfrac{WY}{TY}=\dfrac{1}{2}$

where, WY=30

$\dfrac{30}{TY}=\dfrac{1}{2}$

$TY=2\times 30$

$TY=60$

Hence, The length of TY is 60
