A meter stick perpendicular to the ground casts a 1.5 m shadow. At the same time a telephone pole casts a shadow that is 9 m. How tall is the telephone pole?
keep in mind, the sun, is hitting both the stick and the pole, at the same angle, thus, making and angle of elevation with the ground, the same for both
so, notice the "red" angles, thus the triangles are similar by AA
