Question

An electrical pole breaks at a height of 5 m
from its base due to a thunderstorm. Its top
touches the ground at a distance of 12 m from
the base of the pole. Find the original length of
the pole.An electrical pole breaks at a height of 5 m

the pole.​

Answer 1

Answer:18m

Step-by-step explanation:

12m equals base

side equals 5 m

hypotenuse=12sq+5sq

=144+25=169

length of pole = square root of 169=

13+5m of broken pole=18m

Answer 2

Answer:

Original length of pole is 18m

Step-by-step explanation:

In the picture given below,

PQ: length of the electric pole still standing vertically,i.e, 5m

PR: distance between the base of the pole and the top of the broken pole,i.e, 12 m

QR: the broken part.

now, by Pythagoras theorem

PQ² + PR² = QR²

5² + 12² = QR²

25+144 = QR²

169 = QR²

=> QR = 13

Now, the height of pole: PQ + QR= 5 + 13 = 18m
