Question 178182
Perimeter of a triangle. The perimeter of the triangle
shown in the accompanying figure is 12 meters. Determine
the values of x, x +1, and x +2 by solving the equation
x+(x+1)+(x+2)=12

-----------------------
3x + 3 = 12
Divide thru by 3 to get:

x + 1 = 4

x = 3
-------------------------
side 1: x = 3
side 2: x+1 = 4
side 3: x+2 = 5
------------------
