Answer:

x = 7.5

Step-by-step explanation:

Since the midsegment and the third segment of the triangle are parallel to each other, therefore,

\frac{8 + 10}{8} = \frac{6 + x}{6}

\frac{18}{8} = \frac{6 + x}{6}

\frac{9}{4} = \frac{6 + x}{6}

Cross multiply

9*6 = 4(6 + x)

54 = 24 + 4x

Subtract 24 from each side

54 - 24 = 4x

30 = 4x

Divide both sides by 4

30/4 = x

7.5 = x

x = 7.5
