our height of the pole is 8 feet, while we have our observer 120 ft away |dw:1447713158751:dw|
OpenStudy (mathstudent55):
The height of the pole is the unknown. It is not 8 ft.
OpenStudy (dbzfan836):
hmm, then what is transit?
OpenStudy (mathstudent55):
@LetsLearn2000
Complete the figure I started above.
Place the transit at the far right side. The transit is 8 ft tall.
Then the angle of elevation of the transit tot eh top of the pole is 36 deg.
Try to draw that.
OpenStudy (mathstudent55):
A transit is an optical instrument that is used to measure angles.
The transit sits on top of an 8-foot pole.

Sorry I had went away but I'm back now :)
OpenStudy (mathstudent55):
The pole measures 8 ft + y.
We can find y using trig with the triangle drawn above.
