Answer 1

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)
