Answer:

Explanation:

The two triangles are similar because the corresponding angle in each is equal to the angle corresponding angles in the other.

Put in simpler language. ΔAEB ~ ΔADC by parallel lines properties. If that's the case 10/(10 + 8) = x/(x + 6)

Equation

AE/AD = AB/AC Substitute values

Solution

10/(10 + 8) = x/(x + 6) Cross Multiply

10*(x + 6) = x* (10 + 8) Combine

10*(x + 6) = 18x Remove the Brackets

10x + 60 = 18x Subtract 10x from both sides

8x = 60 Divide by 8.

x = 60/8

x = 7.5
