Answer:

8.5

Step-by-step explanation:

The length of a segment can be found from its end coordinates by using the distance formula:

d = √((x2 -x1)² +(y2 -y1)²)

d = √((8 -2)² +(4 -(-2))²) = √(6² +6²) = √72

d ≈ 8.485 ≈ 8.5

The length of MN is about 8.5 units.

Answer:

Step-by-step explanation:

Use Pythagorean theorem,

base² + altitude² = hypotenuse²

a² + 9² = 12²

a² = 12² - 9²

a² = 144 - 81

a² = 63

a = √63
