Answer:
Step-by-step explanation:
Alright, lets get started.
ABCD and EFGH are given as similar.
Hence their ratios of the sides will be same.
It means:
[tex]\frac{AD}{EH}=\frac{BC}{FG}[/tex]
Putting the values
[tex]\frac{45}{60}=\frac{15}{x}[/tex]
Cross multiplying
[tex]45x = 60*15[/tex]
Dividing 45 in both sides
[tex]x=20[/tex]
Hence the side FG = 20 in : Answer
