Answer:

? = 35

Step-by-step explanation:

The lengths of corresponding sides of similar polygons are in the same ratio.

The sides measuring 48 and 40 are corresponding sides.

The ratio of their lengths is 48/40.

The sides measuring 42 and ? are also corresponding, so they are in the same ratio.

That means we can set up a proportion to solve for the side with length ?.

48/40 = 42/?

Simplify the fraction on the left side.

6/5 = 42/?

Cross multiply.

6 * ? = 5 * 42

Divide both sides by 6.

? = 5 * 7

? = 35
