e 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?

To find the scale factor, we need to compare the lengths of corresponding sides.
In the first triangle, the longest side (base) is 18 inches.
In the second triangle, the longest side (base) is 30 inches.
To find the scale factor, we divide the lengths of the corresponding sides:
30 inches รท 18 inches = 1.666667
Therefore, the scale factor Randee used to create the copy in centimeters is approximately 1.666667 (or 5/3).
So the answer is:
