Question

Two poles 15m high and 6m high are placed opposite to each other across a 8m long
road. Find the distance between their tops.​

Answer 1

Answer:

Let the poles b pole pole b respectively.

height of pole A=15m

height of pole B=6m.

we can easily observe that height of pole A is greater than the hight of pole B.

this is by an extent of 9m.

now the distance between the base of the pole is 8m.

we need find to the distance between the tops

applying pythagoras theorem here

distance between the top of the poles.

root[distance between base + [difference in height ]

=root(81+64)

=root 45m.
