Answer:

22ft

Step-by-step explanation:

Find the diagram attached

Since the triangles are mirror images of each other, this shows that they are similar triangles

Taking the ratio of the sides of the triangle and equating it to a constant, we will have;

5.5/4 = x/16

Cross multiply

4 * x =5.5 * 16

4x = 88

x = 88/4

x = 22ft

Hence the required value of x is 22ft
