用度分秒表示48.12° 用度表示57°7′30〃 计算63°36′-36.36最好带过程,我看一下怎么算的,

1°＝60′ 1′=60″
∴48.12°=48°+0.12°
=0.48°+0.12×60′
=48°+7′+0.2′×60
=48°7′12″
∴57°7′30″=57°+7′+30″÷60″
=57°+7.5′÷60′
=57.125°
∴63°36′-36.36°=63°+36′÷60′-36.36°
=63.6°-36.36°
=27.24°

48.12° =48°+0.12*60'=48°7.2‘=48°7′0.2*60″=48°7′12″
57°7′30〃=57+7/60+30/3600°=57.125°
63°36′-36.36=63°36′-36°21.6’=27°14.4‘=27°14’24″=27.24°

48.12°=48°7‘12’‘
57°7′30〃=57°7.5’=57.125°
63°36‘-36.36°=63.6°-36.36°=27.24°
