Solve for x. The polygons in each pair are similar

Answer: x=11
Step-by-step explanation:
Since its already given that the two polygons are similar, you can build a ratio:
1. [tex]\frac{40}{32} =\frac{2x-2}{16}[/tex]
2. Then cross multiple which will produce [tex]40*16=32*(2x-2)[/tex]
3. Simplify: [tex]=> 640=64x-64[/tex] [tex]=> 704=64x => x=11[/tex]
Tada! Your answer is there. Have a great day! :D
