# 50 + Height and Distance Questions and Answers | Quantitative Aptitude

Height and Distance questions are an important part of the quantitative aptitude section in various competitive exams. These types of questions are covered to test the mathematical and analytical skills of a candidate. These questions are also to assess the geometric understanding and spatial reasoning of a candidate. Height and Distance Problems are asked in exams like CAT, GATE, UPSC, and more.

Start your preparation by solving these questions. In this blog, we will go over the fundamentals of Height and Distance problems, as well as the types of questions asked in previous year exams and how to approach them. This will help you clear your basics and answer these Height and Distance questions.

## What is Height and Distance? What are Height and Distance Problems?

Height is the measurement of a particular object in the vertical direction. Whereas, distance is the measurement of an object from a specific point in the horizontal direction. Height and distance problems typically involve finding the height or distance of an object or point based on given information and geometric principles. Solving these types of questions involves knowledge of strong trigonometric principles.

Height and Distance Formulas:

In this section, you can see different cases while solving the height and distance questions.

Case 1: If the problem in the question focuses on the height of a tower, the distance of an object from the foot of the tower, a building or hill, the angle of elevation, etc., then the given diagram along with the formulas will help.

In right triangle ABC,

sin θ = Opposite/Hypotenuse = AB/AC
cos θ = Adjacent/Hypotenuse = BC/AC
tan θ = Opposite/Adjacent = AB/BC

Case 2: In this case, the commonly solved problems revolve around the movement of an observer. If the observer is moving toward objects like a tower, building, hill, etc., then the angle of elevation increases. The angle of elevation decreases when the observer moves away from the object. In this case, you can use the given formula to find out the distance.

In right triangle given below, d is the distance between C and D.

d = h(cot x – cot y)

Case 3: There can be another case where you can get similar triangles with the same angle of elevation or angle of depression. These questions can be solved with the help of the given formulas.

In right triangle ABC, DE || AB,

Here, triangles ABC and EDC are similar.
Using Thales or BPT theorem we can write the ratio of sides as:
AB/ED = BC/DC
