Answer:
x=43
Step-by-step explanation:
A triangle contains 180
So
82+55+x=180
=>137+x=180
=>x=180-137
Therefore, x=43 (you can use therefore sign instead of therefore)
To find the perimeter, you would add all the sides. Because we know the perimeter, we can represent this as an equation that needs solved.
362 = x + (2x) + (3x + 2), combine the like terms
362 = 6x + 2, subtract 2 from both sides
-2 -2
<u>360</u> = <u>6x</u>, divide both sides by 6
6 6
x = 60 feet
side 1 = 60 feet
side 2 = 120 feet
side 3 = 182 feet
check your work: 60 + 120 + 182 = 362 feet
