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.
