What is the distance. A. (o,o) B. (5,13) ?

Question

What is the distance. A. (o,o) B. (5,13) ?

Answer 1

use pythagoras theorem a62 = b^2 + c^2

difference in x = 5-0 = 5

difference in y = 13-0 = 13

distance^2 = 5^2 +13^2

=25+169

=194

so the distance is the square root of 194  

Answer 2

use the rule   of distance

sqrt [ (13-0)^2 + (5-0)^2] = sqrt [194]=13.928
