英文的高中微积分 pre-calculus
一个飞行员just start on the glidepath for landing at an airport with a runwar of length 9000 ft.The angles of depression from the plane to the ends of the runway are 17.5度和18.8度.
1.找出air distance the plane must travel untill touching down on the near end of the runway,
2.找出 ground distance the plane must travel untill touching down.
3.找开始降落时的飞机高度.
我题意不是很理解

我意译可以么,我微积分也是英文学的放心,一个飞行员要降落,飞机在地面跑道上方,跑道长9000ft.,飞机现在的位置和跑道两端各成17.5度和18.8度角,（飞机那点连上两个端点就是一三角形）
1求三角形的短边
2求飞机在地面上的投影到降落的距离
3求三角形的高
抱歉图画的简陋,对了要用到大边对大角定理,不过这貌似是几何题啊Hmmm
