将21.28°化成用度,分,秒表示的角.将53°40′30″化成用度表示的角21.28°=21°+0.28×60=21º+16′+0.8×60=21º16′48″53°40′30″
42'=0.7°30〃=0.5'=0.008333……°所以36°42′30〃=36.708333……°
=15°48.6'=15.81°
36‘’=36/60=0.6'(15+0.6)/60=0.26°等于12.26°
将19.045°=19°2'42"其中,0.045°=2.7'(乘以60)0.7'=42"(乘以60)同理,43°7′30″=43°7.5'=43.125°30″=0.5'(除以60)7.5'=0.1
=10度+小数点0.26*60取整（15分）,再小数点0.6*60=36秒=10°15′36″
1º=60'=3600''3.775°=3º+0.775º=3º+0.775*60'=3º+46.5'=3º+46'+0.5*60''=3&
13.63
19度36分零秒.0.6*60=36再问：两道再答：56度15分。方法同上
19°13‘48”
0.37°=0.37×60′=22.2′0.2′=0.2×60″=12″34.37°=34°22′12″42″=42′÷60=0.7′17.7′=17.7°÷60=0.295°26°17′42″=26
3.775°=3°+0.775°=3°+0.775*60'=3°+46.5'=3°+46'+0.5'=3°+46'+0.5*60"=3°+46'+30"=3°46'30"73°23′24″=73°+2
15.4度再问：过程。再问：谢谢。再答：15除以60等于0.4再问：噢。我以为是乘。怪不得。。再答：嗯嗯
15°30′=15.5°
121°54′36〃=121°54+36÷60′=121°54.6′=121+54.6÷60°=121.91°
请稍等正在解答再答：22度30分=22.5度弧度π相当于角度180度所以22.5度=π*22.5/180=π/8弧度再问：为什么加个pai呢？公式吗再答：角化弧公式：（角度/180）x派例如：30度（
40又240分之61度
20°15′30〃=20°15.5′=20°+15.5÷60°=20.2583°
解:11°15'=(675/60)°11°15'=(675/60)°*π/180=π/165π/18=180*5π/(18π)=50°这类题你要记住:1°=π/180,1=(180/π)°
