Расчет горки

The application is designed to select a slope, mountain, hill, etc. Using a calculator, you can determine:
- height difference depending on the average angle and length of the slope;
- the average angle of the slope, depending on the difference in height and length of the slope;
- the length of the descent, depending on the difference in heights and the average angle of the slope.
Additionally, the calculator estimates the approximate time and speed of descent of an object from the slope, provided that the object began to move from the apex of the triangle.
