We can start by using the distributive property to add up the lengths of all three sides:
Perimeter = x + (x-4) + (x-4)
Simplifying this expression, we get:
Perimeter = 3x - 8
We know that the perimeter is 19 inches, so we can set up an equation:
3x - 8 = 19
Adding 8 to both sides, we get:
3x = 27
Dividing by 3, we find:
x = 9
Therefore, the measure of x is 9 inches.
Perimeter = x + (x-4) + (x-4)
Simplifying this expression, we get:
Perimeter = 3x - 8
We know that the perimeter is 19 inches, so we can set up an equation:
3x - 8 = 19
Adding 8 to both sides, we get:
3x = 27
Dividing by 3, we find:
x = 9
Therefore, the measure of x is 9 inches.
