Hello! Any help with the following problem is much appreciated. I am enjoying the topic of trigonometry, but I seem to be having a little trouble with bearings. Thank you in advance.
A river has parallel banks which run directly east-west. Kylie takes a bearing to a tree on the opposite side. The bearing is 047*T. She then walks 10 m due east, and takes a second bearing to the tree. This is 305*T. Find:
a. her distance from the second measuring point to the tree.
b. the width of the river, to the nearest metre.
