Solution:

Since the triangles are similar:

  • 26 + 8:x = 8:10

Solving the equation:

  • 34:x = 4:5
  • => 34/x = 4/5
  • => 34 x 5 = 4x
  • => 170 = 4x
  • => x = 170/4 = 42.5

The distance of x is 42.5 ft.

Answer:

D) 42.5 ft

Explanation:

Use ratios of base : height of the similar triangles:

largest triangle = (26 + 8) : x = 34 : x

smallest triangle = 8 : 10

Therefore,


(34)/(x)=(8)/(10)

Cross multiply:


\implies 34 * 10 =8x


\implies 340 =8x

Divide both sides by 8:


\implies x=42.5
