Introduction

Professor Plum is a homeowner with a unique challenge - her yard is irregularly shaped, and she needs to install a brick border around it. However, before she can start laying the bricks, she must cut them to fit the angles of the garden. In this article, we will explore the mathematical measures required to cut the bricks and create a seamless border.

Understanding the Problem

To solve this problem, we need to understand the given measures and how they relate to the angles of the garden. The measures are:

  • m4A = (11x)°
  • m4D = (8x + 33)°
  • m4B = (10x)°

These measures represent the angles of the garden, and we need to use them to determine the angles of the bricks that Professor Plum needs to cut.

Calculating the Angles of the Bricks

To calculate the angles of the bricks, we need to use the given measures and apply some mathematical concepts. Let's start by analyzing the measures:

  • m4A = (11x)°: This measure represents the angle of the garden, and we need to find the angle of the brick that will fit this space.
  • m4D = (8x + 33)°: This measure represents the angle of the garden, and we need to find the angle of the brick that will fit this space.
  • m4B = (10x)°: This measure represents the angle of the garden, and we need to find the angle of the brick that will fit this space.

Using Trigonometry to Solve the Problem

To solve this problem, we can use trigonometry, specifically the concept of complementary angles. Complementary angles are two angles whose sum is 90°. In this case, we can use the measures to find the complementary angles of the bricks.

Let's start by finding the complementary angle of m4A:

m4A = (11x)° Complementary angle = 90° - (11x)°

Similarly, we can find the complementary angle of m4D:

m4D = (8x + 33)° Complementary angle = 90° - (8x + 33)°

And finally, we can find the complementary angle of m4B:

m4B = (10x)° Complementary angle = 90° - (10x)°

Solving for x

Now that we have the complementary angles, we can set up equations to solve for x. Let's start by setting up an equation using the complementary angle of m4A:

90° - (11x)° = (10x)°

Simplifying the equation, we get:

90° = 21x°

Dividing both sides by 21, we get:

x = 4.29°

Now that we have the value of x, we can substitute it into the other equations to find the complementary angles of m4D and m4B.

Finding the Angles of the Bricks

Now that we have the value of x, we can find the angles of the bricks. Let's start by finding the angle of the brick that will fit the space represented by m4A:

m4A = (11x)° Angle of brick = (11x)° = (11 * 4.29)° = 47.19°

Similarly, we can find the angle of the brick that will fit the space represented by m4D:

m4D = (8x + 33)° Angle of brick = (8x + 33)° = (8 * 4.29)° + 33° = 34.32° + 33° = 67.32°

And finally, we can find the angle of the brick that will fit the space represented by m4B:

m4B = (10x)° Angle of brick = (10x)° = (10 * 4.29)° = 42.9°

Conclusion

In this article, we explored the mathematical measures required to cut bricks for an irregularly shaped yard. We used trigonometry to find the complementary angles of the bricks and solved for x to determine the angles of the bricks. The angles of the bricks are:

  • Angle of brick for m4A: 47.19°
  • Angle of brick for m4D: 67.32°
  • Angle of brick for m4B: 42.9°

By following these mathematical measures, Professor Plum can cut the bricks to fit the angles of her garden and create a seamless border.
