An obtuse triangle has side lengths of (5.5x + 6.2y) centimeters, (4.3x + 8.3z )and (1.6z + 5.1y) centimeters. Which expression represents the perimeter, in centimeters of the obtuse triangle? PLZ HELP ASAP :)

The expression represents the perimeter, in centimeters of the obtuse triangle.

Step-by-step explanation:

An obtuse triangle is a triangle where one of the internal angles is obtuse (greater than 90 degrees).

The perimeter of a triangle is the total distance around the outside of a triangle, which can be found by adding together the length of each side. Or as a formula:

where:

a, b and c are the lengths of each side of the triangle.

We know that the triangle has side lengths of , and centimeters. Therefore, the perimeter is
