Answer:
Step-by-step explanation:
I am so sorry I dont know the answer but I can show you how to answer it
ok so I'm going to use the ABC method
a-10
b-3
c-9
c2-?
so your problem is going to end up looking like
c = √(a² + b²)-3
but for the c= do not plug in 9 just answer it as normal and then subtract 3 and boom you have an answer
