. A vertical mast is 83.5m high. Calculate the angle of of elevation of its top
from a point 12cm away on level ground.
Answered by Damon
tan^-1 (height/distance away)
Surely 12 cm is a typo but if true use 0.12 meters
Answered by duduke
sorry Damon can you please explain more
Answered by Damon
tangent of the angle of elevation = height of mast / distance to mast
Answered by Damon
and I simply do not believe you are only 12 CENTIMETERS from the mast.
