A ramp goes from a doorway of a building to the ground. The end of the ramp connected to the doorway is 1 foot above the ground. The distance along the ramp to the building is 5 feet. What is the angle of elevation of the ramp to the nearest degree?

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
