If these two shapes are similar, what is the measure of the missing length n?
n
18 ft
13 ft
26 ft
Since the two shapes are similar, the ratio of corresponding sides will be the same.
Using the sides given, we can set up a proportion:
n/13 = 26/18
Solving for n:
n = 13 * (26/18)
n = 13 * (1.44)
n = 18.72 ft
Therefore, the missing length n is 18.72 ft.
