48°39′+67°31′=?180°-21°17′×5=?
48°39′+67°31′=?180°-21°17′×5=?
48°39′+67°31′
= (48°+67°)+(39′+31′)
=115°70′
=116°10′
180°-21°17′×5
=180°-(21°×5+17′×5)
=180°-(105°+85′)
=180°-106°25′
=179°60′-106°25′
=(179°-106°)+(60′-25′)
=73°35′
(过程够详细了吧?其中有些步骤是可以省略的.)
48°39′+67°31′
=(48°+67°)+(39'+31')
=115°+70'
=115°+1°10'
=116°10'
180°-21°17'x5
=180°-105°85'
=180°-106°25'
=179°60-106°25'
=73°35'
48°39′+67°31′=48°+67°+31′+39′=115°+70′=116°10′
180°-21°17′×5=180°-21°×5-17′×5=180°-105°-85′=75°-85′=73°35′
48°39′+67°31′
=115°70′
=116°10′
180°-21°17′×5
=180°-106°25′
=73°35′
