  71°-24°34'=69°60'-24°34'=45°26'

  15°25'+38°41'=44°06'-16°52'=27°14'

1°=60'

ex 29

  m(<a)+m(<b)=31°42'+25°30'=56°72'=57°12'

  m(<b)-m(<a)=31°42'-25°30'=6°12'

  m(<a)·4=25°30'·4=100°120'=102°

  90°-m(<a)=90°-25°30'=89°60'-25°30'=64°30'

  5·(m<a:2)=5·(25°30':2)=5·(24°90':2)=5·12°45'=60°225'=63°45'

  (4·<b):3=(4·31°42'):3=124°168':3=126°48':3=42°16'
