Draw and explain an angle of elevation of a window is 40 degrees.
To draw and explain an angle of elevation of 40 degrees, follow these steps:
1. Take a blank sheet of paper, a ruler, and a protractor.
2. Start by drawing a horizontal line on the paper to represent the ground or floor.
3. Decide on the scale of your drawing, which means assigning a specific length to each unit on the drawing. For simplicity, let's assume that one unit on the paper is equal to one meter in real life.
4. Mark a point on the horizontal line to represent the position of the window on the ground. Label this point as 'A'.
5. From point A, draw a vertical line upwards, representing the height of the window. Measure and mark a distance of, let's say, 3 units along the vertical line. This will represent the height of the window.
6. Label the top of the vertical line as 'B'. The line AB represents the height of the window above the ground.
7. Now, using the protractor, align its base (the flat side) with the horizontal line, so that the midpoint of the protractor is on point A.
8. Find the 40-degree mark on the protractor and draw a line from point A, passing through the 40-degree mark. This line represents the angle of elevation.
9. Extend the line of the angle of elevation until it intersects with the vertical line AB. Label this point of intersection as 'C'.
10. Now, you have a triangle where the base is AB, the vertical line from A to C is the height of the window, and the line segment AC is the length of the hypotenuse.
To explain the angle of elevation of 40 degrees:
- The angle of elevation is the angle between the horizontal line (the ground) and the line of sight from the observer to the object (the window). In this case, the angle of elevation is 40 degrees.
- It represents the upward tilt of the line of sight from the observer's eye towards the window.
- The angle of elevation is important in various applications, such as surveying, navigation, and engineering, to determine the height or distance of an object by measuring the angle between the horizontal line and the line of sight.
- By knowing the angle of elevation and the distance from the observer to the object, trigonometric functions like sine, cosine, or tangent can be used to calculate the height or distance.
- In the case of the window, knowing the angle of elevation of 40 degrees and the distance from the window, you can use trigonometry to find the height of the window or the distance from your position to the window.
