Question
a surveyor is 3 miles from a mountain. The angle of elevation from the ground to the top of the mountain is 15 degrees. What is the height of the mountain?
Answers
Assuming the 3 miles is the horizontal distance to the "inside" of the mountain, this is a basic tangent ratio
tan15 = height/3
height = 3tan15° = ... miles
tan15 = height/3
height = 3tan15° = ... miles
0.8
