How do I find the length of the altitude in this right triangle​

x=30

step-by-step explanation:

i will pick c put check it over to be sure

step-by-step explanation:

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 : )
