1 Tim was standing at point A when he saw a tree, T, directly opposite him on the far bank of the river. He walked 100 m along the riverbank to point B and noticed that his line of sight to the tree made an angle of 27° with the riverbank. Answer the following to two decimal places. a How wide was the river? b What is the distance from point B to the tree? 27° A 100 m B Standing at B, Tim measured the angle of elevation to the top of the tree to be 18°. c Make a clearly labelled diagram showing distance TB, the height of the tree and the angle of elevation, then find the height of the tree. 2 A yacht, P, left port and sailed 45 km on a bearing of 290°. Another yacht, Q, left the same port but sailed for 54 km on a bearing of 040°. a What was the angle between their directions? b How far apart were they at that stage (to two decimal places)?
