Answer :
each treee has 3 wirds
so 3 feet from the ground
4 feet from the tree
use pythatorean theorem to find staright measure from tree to ground
a^2+b^2=c^2
3^2+4^2=c^2
9+16=c^2
25=c^2
square root both sides
5=c
the legnth is 5
3 wires per tree
3 times 5=15
6 trees
15 times 6=90
90 feet of wire is needed
so 3 feet from the ground
4 feet from the tree
use pythatorean theorem to find staright measure from tree to ground
a^2+b^2=c^2
3^2+4^2=c^2
