Answer:

11.2 mi

Step-by-step explanation:

1. We can use the Pythagorean Theorem (a^2 + b^2 = c^2) to find the missing leg, b, of the triangle.

  • [tex]9^2 + b^2 = 14.4^2[/tex]

2. (Solving)

Step 1: Simplify both sides of the equation.

  • [tex](9*9)+b^2 = 14.4 * 14.14[/tex]
  • [tex]81 + b^2 = 207.36[/tex]  
  • [tex]b^2 + 81 = 207.36[/tex]

Step 2: Subtract 81 from both sides.

  • [tex]b^2 + 81 - 81 = 207.36-81[/tex]
  • [tex]b^2 = 126.36[/tex]

Step 3: Take the square root of both sides and round to the nearest tenth.

  • [tex]\sqrt{b^2} = \sqrt{126.36}[/tex]
  • [tex]b = \sqrt{126.36}[/tex]
  • b ≈ 11.2

Therefore, x = 11.2 mi.

  • Step by step :

x² = (14,4)² - (9)²

x² = 207,36 - 81

x² = 126,36

x = 11,2mi✔
