Angle = chord/radius.
So 10mm/20m.
= 10mm/20000mm.
= 1/2000 is answer.
So 10mm/20m.
= 10mm/20000mm.
= 1/2000 is answer.

1m = .5mm using a scale.

For 10 mm (i.e. 0.01 m) vertical, horizontal is 20 m.
Therefore slope = vertical/horizontal = 0.01/ 20 = 1/2000.
Therefore slope = vertical/horizontal = 0.01/ 20 = 1/2000.

10/20000 = 1/2000.

(10mm/20m) = (10mm/20000mm) = (1/2000).

10mm convert to meters 0.001.
20m.
So, 0.001/20 =1/2000.
20m.
So, 0.001/20 =1/2000.
