Reynaldo rode his bike 2 miles north and 3 miles east. which equation should he use to find the distance, d, that takes him directly back home?

Step-by-step explanation:

Please find the attachment.

Let d represent the distance that takes him directly back home.

We have been given that Reynaldo rode his bike 2 miles north and 3 miles east.

Upon looking at our attachment we can see that distance covered by Reynaldo forms a right triangle, where d is the hypotenuse.

To solve for d we will use Pythagoras theorem.

, where,

a and b = Legs of right triangle,

c = Hypotenuse of triangle.

Upon substituting our given values in above equation we will get,

Therefore, the equation represents the distance, d, that takes Reynaldo directly back home.
