Please tell me how to draw the slope, the first figure

The dimension (coordinate) of a point in the middle of the inclined plane has been marked on the drawing, and then the dimension (coordinate) of the small end of the inclined plane can be calculated
Connect the small end and the known point, and draw a line. The extended line is the line on the slope, and then fillet

3. Road width standard It is said that science Avenue in Zhengzhou high tech Zone will continue to be built to the West. The new road is said to be 120 meters wide. Does this meet the national standard? The standards and guidelines (97 Edition) states that: Expressway road width (m) 60-100 Expressway road width (m) 60-80 Main road width (m) 40-60 Width of secondary trunk road (m) 30-40 From: Shenzhen Planning Bureau
4. How to calculate the width of urban roads and highways? I often see that * * road is 80 meters wide and 8 lanes in two directions, or * * road is 12 meters wide and 4 lanes in two directions. I don't understand it. The first road with 80 meters wide can't get 80 meters when I look left and right, and the visual inspection is 30-40 meters at most (although it's not accurate, but it's not much different. For example, the 50 meter long runway and the 80 meter wide road obviously show that the runway is longer at a glance). Another example is the 8.5 meter wide road, where three people hold hands and are wider than the road, Three people add up to no more than six meters Please give an example. It's better to have a schematic diagram,
