a girl that was 4 and a half feet tall was standing next to a telephone pole. at one 'o clock, her shadow was 8 ft. long, and the pole's was (i think) 36 ft. long, how tall was the pole?
this is from memory, since i forgot to bring the paper home. but i believe that is it.
I don't understand how to start.
you would have similar triangles, so by a simple ratio
h/36 = 4.5/8
h = 36*4.5/8 = 20.25
