camine has 3 pieces of wire . the lenght 1st wire 5 meters the lenght of second wire is 3 meters less than tice the lenght of third wire . what is the peremeter of the triangle if the wires are connected end to end and the scond 9 meters long
if wire 2 is 9, and wire 3 is x, then we have
9 = 2x-3
x = 6
the perimeter is just
5 + 9 + 6 = ?
To find the perimeter of the triangle formed by the connected wires, we need to first determine the length of the third wire.
Given that the first wire is 5 meters long and the second wire is 3 meters less than twice the length of the third wire, let's denote the length of the third wire as "x."
Therefore, the length of the second wire is 2*x - 3. And we know that the length of the second wire is 9 meters.
So, we can set up the equation: 2*x - 3 = 9
To solve for x, we can add 3 to both sides of the equation:
2*x = 12
Divide both sides by 2:
x = 6
Now that we know the length of the third wire, which is 6 meters, we can calculate the perimeter of the triangle formed by the wires.
Perimeter of a triangle is the sum of the lengths of all three sides.
So, the perimeter would be:
5 + 9 + 6 = 20 meters
Therefore, the perimeter of the triangle formed by the connected wires is 20 meters.
