Answer:
22is the answer cuz it is
Step-by-step explanation:
using pythagoras theorem
a^2 + b^2 = c^2
here 4 and 9 are the legs of the right angled triangle so let them be a and b respectively . third side is the hypotenuse because it is opposite to 90 degree so let it be c.
4^2 + 9^2 = c^2
16 + 81 = c^2
97 = c^2
[tex]\sqrt{97} = c[/tex]
