Oct 13, 2025 by pinkandtrash.com 147 views

Introduction

In trigonometry, a bearing is an angle measured clockwise from the north. When a plane flies on a bearing of 50°, it means that the plane is flying at an angle of 50° south of east. In this article, we will use a diagram to determine the distance traveled north and the distance traveled east by a plane flying on a bearing of 50° for 100km.

Understanding the Problem

To solve this problem, we need to understand the concept of trigonometry and how to use it to find the distance traveled in different directions. The bearing of 50° means that the plane is flying at an angle of 50° south of east. This means that the plane is traveling in a direction that is 50° south of the east direction.

Drawing a Diagram

To visualize the problem, let's draw a diagram. We will draw a right-angled triangle with the east direction as the base and the north direction as the height. The bearing of 50° is the angle between the east direction and the direction of the plane.

  +---------------+

  |  50°         |
  |  (bearing)   |
  |               |
  +---------------+
  |               |
  |  East        |
  |  (base)      |
  |               |
  +---------------+
  |               |
  |  North       |
  |  (height)    |
  |               |
  +---------------+

Using Trigonometry to Find the Distance Traveled

Now that we have a diagram, we can use trigonometry to find the distance traveled north and the distance traveled east. We will use the sine and cosine functions to find the distances.

Let's assume that the distance traveled east is x and the distance traveled north is y. We can use the sine and cosine functions to find the values of x and y.

  sin(50°) = y / 100
  cos(50°) = x / 100

Solving for x and y

Now that we have the equations, we can solve for x and y.

  y = 100 * sin(50°)
  x = 100 * cos(50°)

Calculating the Values of x and y

Now that we have the equations, we can calculate the values of x and y.

  y = 100 * 0.766
  x = 100 * 0.642

Calculating the Values of x and y (continued)

Now that we have the equations, we can calculate the values of x and y.

  y ≈ 76.6
  x ≈ 64.2

Conclusion

In this article, we used a diagram to determine the distance traveled north and the distance traveled east by a plane flying on a bearing of 50° for 100km. We used the sine and cosine functions to find the distances and calculated the values of x and y. The distance traveled north is approximately 76.6km and the distance traveled east is approximately 64.2km.

Final Answer

The final answer is:

Distance traveled north: 76.6km
Distance traveled east: 64.2km
