FAQs on Height & distance - 1 Video Lecture - Crash Course for SSC CGL (English)

1. How can height and distance concepts be applied in real-life situations?
Ans. Height and distance concepts can be applied in various real-life situations such as calculating the height of a building, distance between two objects, angle of elevation or depression, etc. These concepts are commonly used in fields like engineering, architecture, surveying, and physics.
2. What are the basic trigonometric ratios used in height and distance problems?
Ans. The basic trigonometric ratios used in height and distance problems are sine, cosine, and tangent. These ratios help in finding unknown sides or angles in a right-angled triangle.
3. How can we determine the height of a tree using the concept of height and distance?
Ans. To determine the height of a tree, we can use the concept of the angle of elevation. By measuring the angle formed between the ground and the top of the tree from a certain distance away, we can calculate the height of the tree using trigonometric ratios.
4. What is the angle of depression in height and distance problems?
Ans. The angle of depression is the angle formed below the horizontal line when an observer looks down at an object. This angle is commonly used in height and distance problems to calculate the vertical distance between the observer and the object.
5. How can we calculate the distance between two objects using the concept of height and distance?
Ans. To calculate the distance between two objects, we can use the concept of the angle of elevation or depression. By measuring the angle formed between the line of sight to each object and the horizontal line, we can apply trigonometric ratios to find the distance between the objects.
