Find the perimeter of a triangle with sides that measure 55 cm, 48 cm, and 32 cm..

The perimeter of the triangle is 135 cm

Step-by-step explanation:

* Lets explain how to find the perimeter of a triangle

- The perimeter of any triangle is the sum of the lengths of its three sides

- The perimeter of the scalene triangle is P = S1 + S2 + S3

- The perimeter of the isosceles triangle is P = 2S + S1

- The perimeter of the equilateral triangle is P = 3S

* Lets solve the problem

∵ The length of the 1st side is 55 cm

∴ S1 = 55 cm

∵ The length of the 2nd side is 48 cm

∴ S2 = 48 cm

∵ The length of the 3rd side is 32 cm

∴ S3 = 32 cm

∵ The triangle is scalene

∴ P = S1 + S2 + S3

∴ P = 55 + 48 + 32 = 135 cm

* The perimeter of the triangle is 135 cm

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
