Two points are located in the Cartesian plane. The first has coordinates $(1\mathrm{.}63$m$,3\mathrm{.}71$m$)$

$,$ and the second has coordinates $(2\mathrm{.}08$m$,4\mathrm{.}04$m$)$

$.$ The diagram is not specific to this problem, but simply illustrates the relationship between Cartesian and polar coordinates.
