This is a right angle triangle problem drawing a vertical line at from the point where the ramp touches the car park leaves a right angle triangle with the opposite being 2m hypothenus being 10m adjacent unknown we could use sine SineO equal to opposite over hypothenus SineO equal to 2/10 SineO equal to 0.2 O equal to Sine^1(0.2) O equal to 11 .5 The angle between the ramp and the horizontal is 11.5 degrees
