3点45分时,时针与分针的夹角为几度?

Seven twenty-two, five fifty, three forty-five,
12 point 02 nine forty-five, twelve thirty-seven,

假设时针不随分针变化 180°
由于时针随分针变化

时间是3点45-3点10=30分钟,个数是30÷5=6个
望采纳

按顺序是：twenty-four past nine
a quarter to eight,
a quarter past ten,
six o'clock,
twenty past eight,
eleven to eight,
a quarter to four,
ten past nine
one to nine
seventeen to eight
nine o'clock
half past eleven
eleven tosix
twenty-two to five
a quarter past six
eight past twelve
twelve o'clock
one past one
four to four
half past four
eleven o'clock
one to four
twenty-one past one
three to four
twenty-eight to three
half past two
half past twelve
nineteen to thirteen
错了包涵下哦!

分针每小时走360°,45分钟=3/4小时,走360×3/4°=270°
时针每小时走30°,3时45分=3又3/4小时=15/4小时,走30×15/4=112.5°
所以时针和分针的最小夹角是270-112.5=157.5°
祝您策马奔腾哦~

60度 180度 3到无数

1点15 - one fifteen,a quarter pass one
3点45 - three fort-five,a quarter to four ,
1点30 - one thirty ,half pass one
3点15 - three fifteen,a quarter pass three
2点30 - two thirty,half pass two
3点30 - three thirty ,half pass three
2点15 - two fifteen,a quarter pass two
1点45 - one forty- five ,a quarter to two
2点45 - two forty-five,a quarter to three

7点40--seven fourty 或 twenty to eight
3点45、three fourtyfive 或 quarter to four
5点30、five thirty 或 half pass five
9点40、nine fourty 或 twenty to ten
6点26、six twenty-six 或 twenty-six pass six
8点、eight 或 eight o‘clock
10点20,ten twenty 或 twenty pass ten

half past four
fifteen to fou

解题思路：首先知道一格等于30°，而时针走一格需要60′，故易求走45′时的角度．

∵在钟面上有12格，一个圆周是360°，
∴1格=[360°/12]=30°，
又∵时针走一格的度数=30°，一格=60′，
∴时针和分针所在直线所成的锐角=30°×[45′/60′]=30°×[45/60]=22.5°．
故答案是：22.5°．

点评：
本题考点： 钟面角．

考点点评： 本题考查了钟面角．注意时针走一格是30°，走一格需要60′．

3:45用英语怎么说
three forty five
forty five past three
a quarter to fou

11点 eleven o'clock
3点15 three fifteen = a quarter past three
2点30 two thirty = half past two
3点45 three forty- five = a quarter to four
5点55 five fifty-five = five to six
