Question from Lin, a student: How do surveyors determine a height of a building 150 feet away with an observation angle at 40 degrees? |
Hi Lin,
Here is my diagram.
What trig function relates the height of the building, $h$ feet, the distance to the base of the building, 150 feet and the measure of the angle, $40^o?$
