Question

Find the length of the segment AB.

Answer 1

Answer: √74 or 8.6

Explanation:

• Formula for distance is √ [ (x2 – x1)^2 + (y2 – y1)^2].
• A(3,9) and B(8,2)
• √[(8-3)^2+(2-9)^2]
• Put that into a calculator and you get √74 which can be rounded to 8.6

Answer 2

8.6

Explanation:

You need to use the Patagorean theorem! :) Just do seven squared and five squared add them up and then square root them!!
