A:
This is a SOHCAHTOA problem A right angle triangle is formed from the ramp, doorway and the ground with the ramp being the hypothenus the elevation angle of the ramp would be the angle the ramp makes with the ground we can use TanO equals to opposite over adjacent TanO equals to 1/5 TanO equals to 0.2 O equal to tan^-1( 0.2) O equal to 11.3 O equal to 11 degree
