Question

An electric pole is 12m high. A steel wire
tied to the top of the pole is affixed at a point.
on the pole ground at a distance 5m
from the foot of the pole. Find the length
of
the wire.​

Answer 1

Answer:

Here H=12, B=5

Using Pythagoras Theorem

$h ^{2} = p ^{2} + b ^{2}$

$12 ^{2} = p ^{2} + 5^{2} \\ 144 = p ^{2} + 25 \\ p ^{2} = 144 - 25 \\ p ^{2} = 119 \\ p = \sqrt{119} m$

Length of wire = root 119 m
