Answer:
return(tempC)
*no space between 'n' and '('
Step-by-step explanation:
just like the first line of code:
def hypotenuse_length(tempF)
there is no space between 'h' and the '('
do not include that space, as doing so will make the program think that you're starting another line, item, object, etc. and not providing the resource the "return" needs (in this case is the 'tempC' within the parenthesis)
