The rise over the distance is equal to the tangent of the angle
Since tan (1 degree) = .0174 then the rise is
.0174x13 = 0.227 meters ( 227 mm)
Approx 1.31 units.
A rise of 1.31 metres.
3.03 feet (rounded)
To calculate the fall over a distance of 1.8 meters for a 5-degree angle, you can use the formula: fall = distance × sin(angle). In this case, fall = 1.8 meters × sin(5 degrees) ≈ 1.8 × 0.0872 ≈ 0.157 meters, or about 15.7 centimeters.
A 1-degree fall over a distance of 3 meters corresponds to a vertical drop of approximately 0.052 meters, or 5.2 centimeters. This is calculated using the tangent of the angle (1 degree) multiplied by the distance (3 meters). In practical terms, this means that for every 3 meters of horizontal run, the roof would drop about 5.2 centimeters.
5*sin(30) = 2.5 metres.
A 140 degree angle is about half way between a 90 degree angle, which has lines that are perpendicular to each other, and a 180 degree angle, which is a straight line. A 140 degree angle is an obtuse angle which has a line a little over half way between the 90 degree and 180 degree angles.
No that is a right angle. An obtuse angle is any angle over 90 degrees.
To calculate the fall (or drop) of an 8-degree roof over a distance of 1 meter, you can use the tangent function from trigonometry. The formula is: fall = distance × tan(angle). For an 8-degree angle, the fall is approximately 1 meter × tan(8°), which equals about 0.14 meters, or 14 centimeters.
A 5-degree fall over 2 meters corresponds to a vertical drop of approximately 0.174 meters, or about 17.4 centimeters. This can be calculated using basic trigonometry, where the vertical drop (rise) is the sine of the angle multiplied by the horizontal distance. In this case, ( \text{Drop} = 2 \times \sin(5^\circ) ).
An angle that is 136 degrees would be an obtuse angle. This is because its degrees are over 90 which is a right angle.
To calculate the fall (or slope) of a 3-degree roof over a distance of 2 meters, you can use the formula: fall = distance × tan(angle). In this case, the fall would be approximately 2 meters × tan(3 degrees), which equals about 0.105 meters, or 10.5 centimeters. Thus, the roof would fall approximately 10.5 cm over the 2-meter span.
