What is the length of AA' , rounded to the nearest hundredth? Type a numerical answer is the space provided. Do not type spaces

inna [77]

Coordinate of A are (0,0)
Coordinates of A' are (5,2)

We can find the distance from A to A' using the distance formula:

$AA'= \sqrt{(5-0)^{2}+ (2-0)^{2} } \\ \\ 
AA'= \sqrt{25+4} \\ \\ 
AA'= \sqrt{29} \\ \\ 
AA'=5.39$

Thus, rounded to nearest hundredth, AA' is equal to 5.39
