A sporting goods store sells triangular team pennants in two sizes. The base of one pennant is 18 in. and the length of the side

juin [17]

This is a proportion problem because the problem stated that the two team pennants are similar.

Pennant 1 = base = 18 in ; length = 9 inches
Pennant 2 = base = 6 in ; length = x ?

9/18 = x/6
9*6 = 18x
54 = 18x
54/18 = x
3 = x

The length of the side of the smaller pennant is 3 inches.
