The angle measure 47°18'41" equivalent to 47.311°
In Math, the degrees are represented by (°), the minutes by (') and the seconds by (''). The relation between these units is given for:
1°=60'=3600'' (One degree is equal to 60 minutes and equal to 3600 seconds).
1°------------- 3600"
x°------------- 41"
[tex]3600x=41\\ \\ x=\frac{41}{3600} =0.01138^{\circ \:}[/tex]
1°------------- 60"
x°------------- 18"
[tex]60x=18\\ \\ x=\frac{18}{60} =0.3^{\circ \:}[/tex]
[tex]47+0.01138+0.3=47.31138[/tex]
Like the exercise asks the result rounded to the nearest thousandth of a degree, the answer is: 47.311°.
