Question

The pair of polygons is similar. Find the value of x.

187. 5 in
12 in
30 in
37.5 in

Answer 1

The ratio of 75 and 30 is 5:2 or 2.5:1. Since both polygons are similar we can say that the ratio of the smaller polygons given side to x is the same as the larger one so we multiply 12 by 2.5 and get 30. 30in is the answer
