Angle of Elevation |

Rita pose la question :
Uluru or Ayers Rock is a sacred place for Aborigines of the western desert of Australia.
Chun-Wei uses a surveying device to measure the angle of elevation to the top of the rock to be 11.5 degrees.
He walks half a mile closer and measures the angle of elevation to be 23.9 degrees.
How high is Ayers Rock in feet?
Stephen La Rocque lui répond. |
