Answer:

  • 1400 mi

Step-by-step explanation:

The triangle CHE is right, angle CHE is marked as right angle.

We have:

  • CD= CH = 3960 mi
  • DE = 240 mi
  • EH = ?

Use Pythagorean theorem to find the value of EH:

  • CE² = CH² + EH²
  • CE = CD + DE = 3960 + 240 = 4200

Substitute known values and solve for EH

  • 4200² = 3960² + EH²
  • EH² = 4200² - 3960²
  • EH² = 1958400
  • EH = √1958400
  • EH = 1399.42 ≈ 1400 mi (rounded)
