Use the Pythagorean theorem to solve this problem. William walks 3.0 miles south and then turns and walks 4.0 miles west. What i

AnnyKZ [126]

Since south and west are at 90 degree angle that means we can use pythagorean theorem to find the distance.

It goes like this:
c^2 = a^2 + b^2

a = 3
b = 4

implementing this in pythagoras formula we get that c = 5

answer is 5 miles southwest

A regular octagon can be concave. True or False? Please explain. Thanks!

kolbaska11 [484]

a regular polygon has all equal angles, interior and exterior, as well as all equal sides.

Check the picture below.

the one on the left is a regular octagon, as well as a convex one.

the one on the right is also an octagon, but is concave, the issue is that, though all sides remain equal, the angles do not, and so is not a regular octagon.
