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.
Perhaps, if you cannot understand true bearings, than attempt it with normal bearings:
A river has parallel banks which run directly east-west. Kylie takes a bearing to a tree on the opposite side. The bearing is N93*E. She then walks 10 m due east, and takes a second bearing to the tree. This is N55*W. Find:
a. her distance from the second measuring point to the tree.
b. the width of the river, to the nearest metre.
