Plz help this paper is past due and I cant get past this one I will give 20 points
*use pythagorean theorem*

Answer 1

Troy is 9.43 miles far from his starting point.

Step-by-step explanation:

Given,

Distance traveled east = 8 miles

Distance traveled north = 5 miles

The distance east and north and coming back will form a right triangle where the distance east and north will form the two legs and coming back to starting point will be the hypotenuse.

Using Pythagoras theorem

$a^2+b^2=c^2\\(8)^2+(5)^2=c^2\\64+25=c^2\\89=c^2\\c^2=89$

Taking square root on both sides

$\sqrt{c^2}=\sqrt{89}\\c=9.43$

Troy is 9.43 miles far from his starting point.
