A helium balloon is rising vertically above point A that is located on level ground directly
underneath the balloon. As it rises for a time period of 1 minute, its angle of elevation from a
point B on the ground that is located 180 meters from point A changes from 13 degrees to 65
degrees. How far does the balloon rise during this period of time? Approximate your answer to
the nearest tenth of a meter.
氦气球上升点位于其垂直向下地面上的气球的正上方。上升时间为1分钟，从点B运动到点A，其仰角度的变化从13度到65度，两点的直线距离为180米。问：在这段时间里，气球上升了多高？请给出大致的高度，答案精确到0.1米。
您好，这是一道数学题，翻译时应按中文表达习惯，译文如下供参考：
一个氦气球垂直从点A升起，点A位于氦气球正下方的水平面上。点B距离点A180米的水平面上，当气球升起1分钟时，其仰角相对于点B从13度变为65度。问：在这段时间，气球升起多高？计算结果精确在0.1米。
一个氦气球在位于其正上方水平面上的A点上空垂直上升.当它上升了1分钟之后,地面上距离A点180米的B点到它的仰角由13度增加到了65度.问这段时间内气球上升了多少距离?答案精确到0.1米 再给你拆开解释下:一个气球垂直上...
