Use the image to answer the question.

An illustration shows two triangles positioned differently. The first triangle has its longest side along the baseline. The second triangle has its longest side in the upper left, and the triangle is tilted upward to the right. The first triangle has a base of 18 inches and sides as 10 inches and 15 inches. The second triangle shows three sides as 30 inches, 36 inches, and 20 inches.

Randee draws these two triangles with lengths given in centimeters. What scale factor does she use to create the copy on the right from the original on the left?

The scale factor is 5, since 18 inches is equal to 90 centimeters and 10 inches is equal to 50 centimeters, 15 inches is equal to 75 centimeters, 30 inches is equal to 150 centimeters, 36 inches is equal to 180 centimeters, and 20 inches is equal to 100 centimeters.
