CN Tower height = 553.33 m

Allen looking angle = 15°

Distance between Ellen and the base of the tower = ?

tan 15 = (CN Tower height) / (Distance between Ellen and the base of the tower)

tan 15 = 553.33 / (Distance between Ellen and the base of the tower)

Distance between Ellen and the base of the tower =  553.33 / tan 15

Distance between Ellen and the base of the tower =  553.33 / 0.267949

Distance between Ellen and the base of the tower =  2065.557 m
