Answer:

√13

Step-by-step explanation:

Given :Reynaldo rode his bike 2 miles north and 3 miles east.

To Find :Which equation should he use to find the distance, d, that takes him directly back home

Solution:

Refer the attached figure.

Reynaldo rode his bike 2 miles north i.e. AB = 2 miles

Then he rode 3 miles east i.e. BC=3 miles

now to find the distance, d, that takes him directly back home i.e.AC

To find AC we use Pythagorean theorem:

Hypotenuse^{2} =Perpendicular^{2} +Base^{2}

d^{2} =AB^{2} +BC^{2}

d^{2} =2^{2} +3^{2}

hence this is the required equation .

d^{2} =4 +9

d^{2} =13

d=\sqrt{13}

Thus the distance, d, that takes him directly back home i.e.AC=√13

Pythagorean theorem - a^2 + b^2 = c^2

2^2+3^2 = d^2
d^2 = 13
d= square root of 13
