Question

Segments WK, XL, and YJ are medians of triangle WXY.

What is the length of segment ZY?

A. 4
B. 5
C. 8
D. 10

Answer 1

10

Explanation:

The median of a triangle, when bisected by other medians has a 2:1 ratio. So the longest part is twice the length of the shorter one. Since median YJ is 15, when divided by 3, it has equal parts of 5. 5*2= 10. And so segment ZY is equal to 10.
