Answer:

Answer is 20.

Step-by-step explanation:

Since they are similar thus ratio of sides would be equal the top side is double of the first polygon. so the side x wud be double of 10. which is 20

Answer:

x = 20

Step-by-step explanation:

Since the polygons are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{5}{10}[/tex] = [tex]\frac{10}{x}[/tex] ( cross- multiply )

5x = 100 ( divide both sides by 5 )

x = 20
