Answer:

10cm

Step-by-step explanation:

let the third side be x

perimeter of triangle = side + side + side or 3× side

12+14+x=36

26+x=36

x=36-26

x=10cm

Answer 2

Answer:

as u know triangle has 3 sides and the definition of perimeter is sum of all sides of triangle so by that

perimeter of triangle = sum of all three sides of triangle

                             36  = 12+14+3rd side

                             36  = 26+3rd side

                        36-26 = 3rd side

                             10  = 3rd side

     sides of triangle = 12,14,10
