Answer:

1 leg = 12 inches

Explanation:

We can use the equation:

43 = 2x + (7 + x)

To represent the perimeter of the isosceles triangle. We can simplify the problem by adding the variables on the right side.
43 = 3x + 7

Next, we can subtract 7 from both sides to isolate the variable.

3x = 36

Since we know that 36 is divisible by 3, we can divide both sides by 3:

3x/3 = 36/3

x = 12

Our final answer is x = 12 inches. So, the length of one leg is 12 inches.
