Question

a 5-foot tall girl casts a 7-foot long shadow. a nearby telephone pole casts a 35-foot long shadow. what is the height of the telephone pole?

Answer 1

25 feet.

Explanation:

The triangles formed are similar so:

5/h = 7/35 where h = height of the pole.

7h = 5*35

h = 5*35/ 7

h = 5*5

h = 25.
