2 . 湖北宜昌三峡大瀑布是国家4A级景区,也是神农架探秘的必经之地.是展示震旦纪、奥陶纪、寒武纪等多个地质年代的天然地质博物馆,也是世界上少有的集峡谷、溶洞、山水、化石文化为一体的国家级地质公园,以山青、水秀、洞奇、瀑美著称.走进景区,犹如展开一幅绝美的山水画卷,这里完全远离了都市的尘嚣和喧闹,在树林间穿行,你可以尽情地呼吸着那没有任何污染的富含负氧离子的空气,你会犹如置身世外,忘掉一切烦恼,你能体会到的只有一个字--"幽".群山如黛,峡谷幽深,奇石林立,瀑布层叠,原生植物茂盛,生态环境原始自然,自然景观独具特色.峡谷内溪水常年不断,构成30多道形态各异的瀑布镶嵌于峡谷内,其中最壮观的是高102米、宽80米的三峡大瀑布,游瀑中全国独一无二的零距离"穿越"大瀑布,让人充分感受"集体湿身"的欢快和刺激.为了测量湖北宜昌三峡大瀑布的某一处实际高度,李华同学设计了如下测量方案:有一段水平山道,且山道与瀑布不在同一平面内,瀑布底端与山道在同一平面内,可粗略认为瀑布与该水平山道所在平面垂直,在水平山道上A点位置测得瀑布顶端仰角的正切值为
,沿山道继续走
,抵达B点位置测得瀑布顶端的仰角为
;已知该同学沿山道行进的方向与他第一次望向瀑布底端的方向所成角为
,则该瀑布的高度约为( ).
