Find the side length and round your answer to the nearest hundredth.

√180 or 5√6

Step-by-step explanation:

Plug in: a^+b^2=c^2

a^2+12^2=18^2

a^2+144=324

subtract 144 from both sides

a=√180

a= 5√6

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.
