Answer:
- The epicenter is ( - 2, 3)
Step-by-step explanation:
Let the epicenter be E(x, y).
Use the distance formula for each given distance:
- AE² = (x + 2)² + (y - 5)² = 2²
- BE² = (x - 2)² + (y - 3)² = 4²
- CE² = (x + 2)² + (y + 4)² = 7²
Use the first and third equations, considering both have same term for x, and solve for y:
- (y - 5)² - 4 = (y + 4)² - 49
- y² - 10y + 25 - 4 = y² + 8y + 16 - 49
- 18y = 54
- y = 3
Substitute y into one of equations and solve for x:
- (x + 2)² + (3 - 5)² = 4
- (x + 2)² + 4 = 4
- (x + 2)² = 0
- x + 2 = 0
- x = - 2
The epicenter is E( - 2, 3)
Answer:
√39
Step-by-step explanation:
use the Pythagorean Th because the triangle is right
8² = 5² + x²
8²-5² = x²
√64-25 = x
√39 =x
