- We can create a right triangle with legs = 10 cm and 8 cm.
- Question asked about closest straight line distance - the same as the hypotenuse of triangle JGH.
- Hypotenuse = \(\sqrt{10^2+8^2} = \sqrt{164}\)
- Approximately, it is closer to 13 (\(13^2 = 169\), 5 more than 164).

Answer is B. It forms the right angle triangle and we just need to find hypotenuse of it. Which is 164^1/2. This is close to 169^1/2 which is equal to 13

Using the information in the stem, we see that the distance between Town H and Town J is the hypotenuse of a right triangle with legs of 8 and 10. Thus:

8^2 + 10^2 = x^2

164 = x^2

√164 = √x^2

√164 = x

Since 164 is close to 169, √164 ≈ √169 = 13.

Check the diagram below:



\(x=\sqrt{10^2+8^2}=\sqrt{164}\), which is little less than 13^2 = 169.

Answer: B.

Why is it not 6 because of a 6-8-10 triangle?
