what is the hietgh difference between 2 walls 6 metres apart to get a 17.5 degree pitch

let x be the height difference.

According to the sketch I made
tan 17.5° = x/6
x = 6tan17.5 = 1.89 metres

To calculate the height difference between two walls at a given distance apart to achieve a specific pitch angle, you can use trigonometry.

Let's assume the distance between the two walls is 6 meters. We need to find the height difference that results in a 17.5-degree pitch angle.

Step 1: First, convert the pitch angle from degrees to radians. To do this, divide the angle by 180 and multiply by π (pi).

17.5 degrees = (17.5/180) * π ≈ 0.305 radians

Step 2: Use the tangent function (tan) to calculate the height difference. The formula is:

Height difference = Distance * tan(pitch angle)

Height difference = 6 * tan(0.305)

Step 3: Calculate the height difference using a calculator. After performing the multiplication and trigonometric function, you will get the height difference.

Height difference ≈ 1.351 meters

Therefore, to achieve a 17.5-degree pitch angle between two walls 6 meters apart, there needs to be a height difference of approximately 1.351 meters.
