$92^{\circ}$ $33'$

Work Step by Step

To convert $92.55^{\circ}$ to degrees and minutes, let's break it as- $92.55^{\circ}$ = $92^{\circ}$ + $0.55^{\circ}$ Now on multiplying 0.55 by 60, we have the number of minutes equivalent to 0.55° Therefore $92.55^{\circ}$ = $92^{\circ}$ + $0.55(60')$ $92.55^{\circ}$ = $92^{\circ}$ + $33'$ $92.55^{\circ}$ = $92^{\circ}$ $33'$
