答案

41°13′26〃化为度是=41+13/60+26/3600=41+0.216667+0.0072222=41.223488888°
37.24°=37°14'24"
8点15分时针与分针所夹的小于180°的角为156°30′
Li lei,I invite you to my home to look my pet dog.He's my best friend from my childhood.I always play with him.Many children of my neighbour like him very much.You can take bus to my home.My home is on the Shanghai road,No,18.Take No.123 Bus to the end stop.Go straight to the cross and turn right,you'll find my house.
因为5x-7与4x+4互为相反数,所以5X-7+4x+4=0 x=1/3 x^3=1/27
