The perimeter of the rectangle shown is 36 inches. Write and solve an equation to find the value of x.

Step-by-step explanation:

Because we know that 1 side is 12, we can multiply it by 2 to find part of the perimeter, which is 24. Now we know that the other 2 sides add up to 12. That means that they each measure 6, so x = 3. The real question is why it shows that 6 is longer than 12!

step-by-step explanation:

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
