A surveyor measures the distance across a straight river
by the following method: Starting directly across from a
tree on the opposite bank, she walks 100 m along the
riverbank to establish a baseline. Then she sights across
to the tree. The angle from her baseline to the tree is
35.0°. How wide is the river?

Moves 100 metres....
So that the angle to the tree is 35 degrees|dw:1367154463542:dw|
