Use a proportion to find the missing side length in the following similar figures. Answers : = 28 cm x = 28 cm x = 30.8 cm x x = 6.4 cm x = 19 cm Pick the correct answer

x = 6.4 cm

Explanation: Since the figures are similar, we can set up a proportion using the corresponding side lengths:

28 cm / x = 19 cm / 6.4 cm

Cross multiplying, we get:

28 * 6.4 = 19x
179.2 = 19x
x = 179.2 / 19
x = 6.4 cm

Therefore, the missing side length is 6.4 cm.
