47PRACTICE PROBLEM
An observer from a helipad (the highest level on a building) sights a stone on the ground using a telescope. The angle of depression of the line of sight of the observer is 26° 30'. Calculate the distance from the stone to the observer. The building has a height of 118 m and the height of the observer can be considered negligible. Round your answer to one decimal place.
