Answer 1

Check Diagram in pic

Solution

AB=47m
BC=18m

using Pythagoras

AB²+BC²=AC²

47²+18²=AC²

2209+324=AC²

2533=AC²

$ac = \sqrt{2533}$

Length of wire =50.3289m


This is ur ans hope it will help you

Answer 2

Answer:

AB=47m

BC=18m

using Pythagoras

AB²+BC²=AC²

47²+18²=AC²

2209+324=AC²

2533=AC²

ac = \sqrt{2533}ac=

2533

Length of wire =50.3289m
