the following two pentagons are similar. find the missing side length represented by x. please help quickly!

5 inches.

Step-by-step explanation: Take a length from the original (13.5) and divide it by the new length of that side (9) to get 1.5. Then take 7.5 and divide it by 1.5 to get 5 inches.

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
