the hardware store is 5 blocks east of john's house. sean lives 3 blocks west of the bank, which is 4 blocks south and 2 blocks west of the hardware store. how many blocks and in what direction is sean's house from john's house?
d=5 @ 0o + 4 @ 270o + 2 @180o + 3 @ 180o.
X = Hor. = 5 + (-2) + (-3) = 0.
Y = Ver. = 4 Blocks.
d^2 = X^2 + Y^2 = 0 + 16
d = 4 Blocks, South.
