When building a ramp, it's essential to consider the relationship between its length, vertical rise, and horizontal distance. This relationship is governed by the principles of geometry and trigonometry. In this article, we'll explore how to calculate the horizontal distance of a ramp given its length and vertical rise.

The Basics of Ramp Geometry

A ramp is a triangular structure with a horizontal base (the ramp length) and a vertical side (the vertical rise). The horizontal distance, also known as the base of the triangle, is the distance from the base of the ramp to the point where the ramp meets the ground. To calculate the horizontal distance, we need to understand the relationship between the ramp length, vertical rise, and the angle of the ramp.

The Pythagorean Theorem

The Pythagorean theorem is a fundamental concept in geometry that describes the relationship between the lengths of the sides of a right-angled triangle. The theorem states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Mathematically, the Pythagorean theorem can be expressed as:

a^2 + b^2 = c^2

where a and b are the lengths of the two sides that form the right angle, and c is the length of the hypotenuse.

Applying the Pythagorean Theorem to Ramp Geometry

In the context of ramp geometry, the Pythagorean theorem can be used to calculate the horizontal distance (c) given the ramp length (a) and vertical rise (b). The ramp length is the base of the triangle, and the vertical rise is the height of the triangle.

Using the Pythagorean theorem, we can write:

a^2 + b^2 = c^2

where a = 16 inches (ramp length), b = 4 inches (vertical rise), and c = horizontal distance (unknown).

Solving for the Horizontal Distance

To solve for the horizontal distance (c), we need to plug in the values of a and b into the Pythagorean theorem equation.

16^2 + 4^2 = c^2

256 + 16 = c^2

272 = c^2

To find the value of c, we need to take the square root of both sides of the equation.

c = √272

c ≈ 16.5 inches

Comparing the Calculated Value to the Answer Choices

Now that we have calculated the horizontal distance (c) using the Pythagorean theorem, we can compare it to the answer choices.

A. 21 inches B. 5 inches C. 15.5 inches

Our calculated value of approximately 16.5 inches is closest to answer choice C. 15.5 inches.

Conclusion

In conclusion, we have used the Pythagorean theorem to calculate the horizontal distance of a ramp given its length and vertical rise. By applying the theorem, we have found that the horizontal distance is approximately 16.5 inches. This value is closest to answer choice C. 15.5 inches.

Additional Tips and Considerations

When building a ramp, it's essential to consider the safety and accessibility of the ramp. The horizontal distance of the ramp should be sufficient to allow users to safely navigate the ramp. Additionally, the ramp should be designed with a gentle slope to prevent accidents.
