helper,
If your draw a sketch of this you will see that a right triangle can be formed.
The base of the right triangle is 37 and the other leg is 23. The hypotenuse is the wire.
Using the Pythagorean theorem,
c^2 = 23^2 + 37^2
Solve for c

Alex,
A^2 +B ^2 = C^2
23^2 + 37 ^2 = C^2
529 + 1369 = C^2
1898 = C ^2
Square root both 1898 Calculator.
After you square root it will be C = 43.56
