Need Help with one multiple choice question. [Medal & Fan]
ah, trigonometry.
Try drawing a figure to represent the situation.

I'll start the figure for you. |dw:1447713131135:dw|
our height of the pole is 8 feet, while we have our observer 120 ft away |dw:1447713158751:dw|
The height of the pole is the unknown. It is not 8 ft.
hmm, then what is transit?
@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.
A transit is an optical instrument that is used to measure angles. The transit sits on top of an 8-foot pole.
I am sorry that I will be unable to assist in this. Goodbye!
@LetsLearn2000 Are you still there?

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