Answer:
11700
Step-by-step explanation:
The triangles are similar (presumably) because their ratios are the same for all three corresponding sides.
Equation
- Set up the proportion
- AB/AC = AD /AE
Givens
- AB = 5600 feet
- AD = 5200 feet
- AC = 5600 + 7000 = 12600 feet
- AD = ?
Solution
- 5600 / 12600 = 5200 / x Cross multiply
- 5600x = 12600 * 5200 Simplify the right.
- 5600x = 65,520,000 Divide by 5600
- x = 65,520,000/5600 Do the division
- x = 11,700
