I need help please thanks

i think that you should ask google for the answer to that problem because if we don't know it google does

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )

the answer is x=45 because i said so
