Please Help!!!!! Branliest and Extra Points will be given!!!!

Answer:
The "a" and "b" in the Theorem will be height and half the length of one side, and "c" will be slant height, since slant height is the hypotenuse of the triangle
Step-by-step explanation:
[tex]a^{2} + b^{2}[/tex]= [tex]c^{2}[/tex]
[tex]22^{2} + 11^{2} = 784 + 121 =[/tex] 905
[tex]= \sqrt{905}[/tex]
= 30.083217913
I am pretty sure about it
But mark me the brainliest!
