Question

The figures are similar. Find the length of the side marked x.
-
A) 38 
B) 32 
C) 50 
D) 40

Quizplus · Accepted Answer

Since the figures are similar, we can set up a proportion:

(original figure side length) / (x) = (corresponding side length in new figure) / (same unknown length in new figure)

Plugging in the given values, we get:

20 / x = 30 / 50

Solving for x, we get x = 40. Therefore, the length of the side marked x is 40. The correct answer is choice D.
