Question

In a strong, storm a hydro pole snapped at the base and fell against a house wall. If the top of the pole was resting 4.8 m above the ground and the bottom of the pole was 12.4 m from the house, how long was the hydro pole (to one decimal place)?

Answer 1

The pole is √(4.8² + 12.4²) = 13.3 m

Answer 2

Asma,

 

4.8 m is the answer. The pole is not long enough to rest against the house wall, so its length is the distance from the ground to its tip, 4.8 m.
