Use a proportion to find the missing side length in the following similar figures.

Question

Two similar and adjacent triangles are shown. The diagonal side of the larger triangle is labeled 12 meters, the horizontal side is labeled 8 meters, and there is a box in the angle across from the diagonal side. The diagonal side of the smaller triangle is labeled x, the horizontal side is labeled 4 meters, and the angle across from its diagonal is a linear pair with the angle with the box in it from the larger triangle.

x = 24 cm

x = 8 m

x = 6 m

x = 8 m

Answer 1

x = 6 m
