The perimeter of the triangle is 20.6 centimeters what is the unknown side length of the triangle let side 3 equal the letter t in your equation side 1 e=6.3cn side 2= 8.4 cm side 3 =t

Respuesta :

The measure of the third side of the triangle is 5.9cm

Let the sides of the triangles be a, b and c. The perimeter of the triangle will be expressed as:

  • P = a + b + c

Given the following parameters:

a = 6.3cm

b = 8.4cm

P = 20.6cm

c = t

Substitute the values into the formula:

20.6 = 6.3 + 8.4 + t

20.6 = 14.7 + t

t = 20.6 - 14.7

t = 5.9cm

Hence the measure of the third side of the triangle is 5.9cm
