有冇人可以幫我解答以下一些數學問題ar??>.
發問:
1.)Lawrence walks 200m up a slope with the gradient of 1/5.What is his vertical rise?? 2.)A ship sails 15 km to the east fromA to B,and then sails 10 km to the north to C.Find the bearinf of a from c.(correct your answer to 1 decimal place.)
最佳解答:
1) 佢所講的200m 應該是一個直角三角形的斜邊, 而gradient of 1/5就係vertical rise / horizontal run, 所以你要先找出gradient of 1/5即係代表幾度. Let tanA be the gradient 1/5, tanA = 1/5 A = 11.3度 (Corr.to 3sig.fig) Let xm be the length of his vertical rise, sin11.3度 = x/200 x = 39.2 (Corr.to 3sig.fig) 2) angle ACB=
其他解答:
你唔係話英文好confusing咩, e+咪一樣答得好好地 睇嚟你都係想線我多wor~
