two sides of a triangle have the same length. the third side measures 6 m less than twice the common length. the perimeter of th
Y_Kistochka [10]

Let x be the length of the two sides that are the same.

Then the third side would be 2x -3.

The perimeter of the triangle will come from adding all of the sides together and setting it equal to the value given, 13.

That is,

x + x + (2x - 3) = 13

-- > 4x - 3 =13

-- > 4x = 16

-- > x = 4.

As for the answer, the question was cut short, but with x=4,,

the length of each of the common sides is 4, making the third side 5, to get a total perimeter of 13.

<h3>What are two sides of a triangle?</h3>

You may determine the sides of a right-angled triangle using a number of techniques, such as the Pythagoras theorem or the triangle's perimeter.

Answer:

a² = 144

b² = 25

c² = 169

c = 13

Step-by-step explanation:

• a² = 12×12

= 144

• b² = 5×5

= 25

• a² + b² = c²

= 144 + 25 = 169

• c = _/169

= 13
