the side view of a shed ,PQRS is the wall of the shed which stands vertically to the ground. PS is the roof which makes an angle of 18degree with the horizontal.Given that PQ=5m and QR=8m and M is a point due south of Q on the ground such that MQ=20m,find
(1)the length of SR
(2)the angle of elevation of S from M
(3)the bearing of R from M
(4)the length PS

这应该是希望杯的题吧
我帮你翻译下
大致意思是 面PQRS是垂直于地面的一个平面
PS挨着地面 和地面成18°角
现已知PQ为5米 QR为8米 点M是在Q的下方 MQ=20米
求 SR的长度
从点M看点S的仰角
点M位于点R的方向?(这个不确定)
PS的长度
就这么多啦 如果你给多点分 我会考虑帮你做下这道题
