数学题：（180°-91°32'24'')÷3 34°25'×3+35°42'
数学题：（180°-91°32'24'')÷3 34°25'×3+35°42'
数学题：（180°-91°32'24'')÷3 34°25'×3+35°42'
（180°-91°32'24'')÷3
=88°27'36''÷3
=87°87'36''÷3
=29°29'12''
34°25'×3+35°42'
=102°75'+35°42'
=137°117'
=138°57'
你这是两个式子吗?@_@
(1)原式=88°27'36"÷3=29°29'12"
(2)原式=103°15'+35°42'=138°57'
1.解:原式=(179°59′60″-91°32'24'')÷3 =88°27′36″÷3=29°29′12″
2.解:原式=102°75′+35°42′=137°117′=138°57′
注明除法
88°27′36″)÷3=29°......1°27′36″
1°27′36″=87′36″
87′36″÷3=29′12″
60分为一度，估计你是不懂这个换算。
29。29'12''
138。57'
数学题：（180°-91°32'24'')÷3 =(179°59'60''-91°32'24'')÷3=88°27'36''÷3=87°87'36''÷3==29°29'12''
34°25'×3+35°42'=102°75'+35°42'=103°15'+35°42'=(103°+35°)+(15'+42')=138°57'.
（180°-91°32'24'')÷3 =（179°59'60''-91°32′24″）÷3 =88°27′36″÷3 =88/3°9′12″ 34°25'×3+35°42' =102°75′+35°42' =137°117′ =138°57′
