问题原文an airplane can fly with a maximum air velocity of 750hm/h[N].If the wind velocity is 60km/h[15°E of N],what must be the plane's ground velocity if it is to remain on a course going straight north?
我翻译的不太标准,所以实在看不懂上面的看我:一架飞机的的最高时速750km/h往北,如果风力是60km/h 15°[E of N](正北15度往西),那么如果这架飞机要飞往正北方,它的实际速度是多少和航向应该是多少度?
我TM想了半小时了!
平行四边形的对角线怎么求……我忘了^^^

解一个平行四边形,两个边长分别是60和750,锐角是15度,求较长的对角线长度(速度),和此对角线与750边的夹角度数(方向),用平行四边形求面积的公式计算.
