Use the picture to help you answer the question.
Make sure to:
-ID the legs and hypothenuse
-Plug in those values into  $a^2+b^2=c^2$  

-Simplify the exponents
-Get the variable by itself
-No need to take the square root this time:)

•  $\sqrt{20}$  

•  $\sqrt{21}$  

•  $\sqrt{40}$  

•  $\sqrt{58}$
