Asked by DeJohn
A biologist wants to know the width w of a river to properly set instruments for an experiment. From point A, the biologist walks downstream 100 feet and sights to point C (see figure). From this sighting, it is determined that
π = 50Β°.

you don't say how π is measured, but if C is directly across from A, and the width is w, then
w/100 = tanπ
or
w/100 = cotπ
w/100 = tanπ
or
w/100 = cotπ
