Answer 8

can it be all?

Answer 9

I only
II only
I and III only
II and III only
I, II, and III

Answer 10

now you could check using cos/tan to figure out the other sides, which will prove statement two correct..
cos 55 = 5 / h
h cos 55 = 5
h = 5/cos 55
h = 8.7~

5^2 + b^2 = 8.7^2
25 + b^2 = 75.69
b^2 = 50.69
b = 7.11969
therefore

a < b < c

Answer 11

or in this case
AC < AB < BC

Answer 12

It's just II only.

Answer 13

ok thaanks!
