Question

Which of the following choices is closest to the distance (in miles) between points A and B?

3.16 miles
3.46 miles
4.47 miles
4.90 miles

Answer 1

This is a right angle triangle, so you can simply use Pythagoras:

`(AC)^(2) = (AB)^(2)+(BC)^(2)`
This means that

`(AB) = \sqrt{ (AC)^(2)-(BC)^(2)}= \sqrt{ (6)^(2)-(4)^(2)}=4.47miles`
The answer is 4.47miles.

Hope this helps!
