Question: If triangle STU is similar to triangle VWX, and ST = 5 cm, TU = 10 cm, and VW = 15 cm, what is the length of side WX?
Options:
Correct Answer: 20 cm
Solution:
Since the triangles are similar, the ratio of corresponding sides is constant. Therefore, WX = (TU / ST) * VW = (10 / 5) * 15 = 2 * 15 = 30 cm.
