Question

What is the distance between the points (80,55) and (20,44)

Answer 1

distance formula : d = sqrt (x2 - x1)^2 + (y2 - y1)^2
(20,44)...x1 = 20 and y1 = 44
(80,55)..x2 = 80 and y2 = 55
now we sub and solve..
d = sqrt (80 - 20)^2 + (55 - 44)^2
d = sqrt ((60^2) + (11^2))
d = sqrt (3600 + 121)
d = sqrt 3721
d = 61 <==
