Answer
$17.3^{\circ}$
Work Step by Step
To convert $17^{\circ} 20'$ to decimal degrees, let's break it as-
$17^{\circ} 20'$ = $17^{\circ}$ + $20'$
Now on dividing $20'$ by 60, we have the number of "decimal degrees" equivalent
to $20'$ (as $ 1^{\circ} = 60'$)
Therefore
$17^{\circ} 20'$ = $17^{\circ}$ + $(\frac{20}{60})^{\circ}$
$17^{\circ} 20'$ = $17^{\circ}$ + $0.333...^{\circ}$
$17^{\circ} 20'$ = $17^{\circ}$ + $0.3^{\circ}$ (Rounding to the nearest hundredth)
$17^{\circ} 20'$= $17.3^{\circ}$
