A triangle has sides of lengths 4.2, 5.7, and 7.2 inches. The smallest side of a similar triangle is 1.4 inches. What are the lengths of the other two sides? Write the smaller side length first and the larger side length second.

Answer 1

If the smallest side of the original triangle is 4.2 inches, and the smallest side of the similar triangle is 1.4 inches, then the scaling factor is 1.4/4.2 = 1/3.
Therefore, the lengths of the other two sides of the similar triangle are 1/3 * 5.7 = 1.9 inches and 1/3 * 7.2 = 2.4 inches.
The lengths of the other two sides of the similar triangle are 1.9 inches and 2.4 inches.
