Question

two electric poles are erected on the ground. the heights of the poles are 20m and 28m respectively. the distance between the poles is 15m. to join the top of the poles how much wires will be required?​

Answer 1

Firstly know that the difference between the height of the two poles is 8m and so you can easily visualise that it makes a right angled triangle and so you can use the Pythagoras theorem which will be IN SQUARE ROOT 8^2 +15^2
This is how you”ll get your answer
