Question

A wire is attached to an upright pole 6 meters above the ground. If the wire is anchored to the ground 4 meters from the base of the pole, how long is the wire

Answer 1

I believe this is Pythagorean theorem
The equation is
a^2+b^2+=c^2
In this case the equation would be
6^2+4^2=c^2
36+16=c^2
52=c^2
c=7.21110255093
