A man walks 1 mile north. He then walks a distance heading west. If he finishes 1.7 miles from his starting point how far did he walk west

1.4 miles

Step-by-step explanation:

If you sketch this out it makes a triangle and you have to find the missing side.

the formula is a^2 + b^2 = c^2

a^2 + 1^2 = 1.7^2

a^2 + 1 = 2.89

       - 1     - 1

a^2 = 1.89

sqrt    sqrt(1.89)

a = 1.37477
