1.53°45′35″12.15013.23114
53°45’35”1502318或12
11..53度45分35秒
11.根据定义，∠α的余角的度数是90°-36°14′25″=53°45′35″．故答案为53°45′35″．12.210度/150度（看你从左边的夹角还是右面的夹角了）13.x(x+1)&100,x2+x-100&0x&（-1+ ）/2（因为x&0）x&9.6即可，可选x=10,11,12…结果如下：x= 3 x= 4 x= 5 x= 6 x= 7 x= 8 x= 9 x= 10 110x= 11 132x= 12 156x= 13 182x= 14 210x= 15 24014.解:分类讨论:(1),C在AB右边:∵AB=10cm,BC=4cm,∴AC=AB+BC=10+4=14cm.∵M为AC中点,∴AM=AC=
7cm.[来源:Z。xx。k.Com]
如图②,C在AB之间:∵AB=10cm,BC=4cm,∴AC=AB-BC=10-4=6cm.∵M为AC中点,∴AM=AC= 3cm.
综上所得AM=7cm或3cm.手打也不容易，把分给我吧
