Question

YM is a median of the triangle below. XM = 2x + 2 and ZM = 4x - 8. What 5 points

is the length of XM?

12
16
-2
10

Answer 1

Option A: 12

Explanation:

From the image of the triangle given, we can see that:

XM = ZM

We are given that:

XM = 2x + 2 and ZM = 4x - 8

Thus;

2x + 2 = 4x - 8

Rearrange to get;

4x - 2x = 8 + 2

2x = 10

x = 10/2

x = 5

Thus, XM = 2(5) + 2

XM = 12
