to determine the height of a pole across a freeway Justin takes 2 measurements he stands at point A directly across from the pole and determines the angle of elevation to the pole is approximately 15.3°. he then walks 30 parallel to the freeway to point C where he sees that the base of the pole and point A are 57.5° apart. from point a the base of the pole and point 3 are 90° apart. calculate the height of the pole to the nearest metre
