Answer:
Step-by-step explanation:
2X + 1 + 3X - 2 + 4X - 5 = 180
9X - 6 = 180
9X = 174
9 = 174

9 9
X = 19.333
The perimeter of the triangle in terms of x given the three side lengths is 9x - 6.
A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees.
The perimeter of a triangle = sum of the side lengths
(2x + 1) + (3x - 2) + (4x - 5) = 9x - 6
