Transit Tripod
March 4th, 2010
Trigonometry Help Please?
To determine the height of a bridge support column, a surveyor uses a transit mounted on a tripod. The transit sits vertically 1.5m above ground level and is placed 20m from the base of the column. The angle to the top of the column is 60 degrees from the horizontal.
a)Determine the height of the coloumn.
b)Determine the transit’s angle of declination from the horizontal to the base of the column.
**Please show all steps so i can follow through!**
<< Determine the height of the column. >>
tan 60 = y/20
y = 20(tan 60)
H = height of column = 1.5 + y
H = 1.5 + 20(tan 60)
H = 36.14 m
<< Determine the transit's angle of declination from the horizontal to the base of the column. >>
tan α = 1.5/20
α = arc tan 1.5/20
α = 4.29 degrees
Hope this helps.
