Answer to Problem 25HP
True. The angle of elevation is increases when a person moves closer to an object
Explanation of Solution
Given information:
The given ststemnet is:
‘The angle of elevation is increases when a person moves closer to an object.’
If a person moves closer to an object, then the horizontal distance decreases. Notice that the vertical distance is a constant.
So, the tangent ratio is calculated by using the following expression:
Tangent ratio is increases because the numerator is fixed and the denominator decreases.
Thus, the angle of elevation increases by properties of tangent
Therefore, the given statement is true.
