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?

Respuesta :

notice the picture below

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

solve for "x"
