You are graphing Square ABCDABCDA, B, C, D in the coordinate plane. The following are three of the vertices of the square: A(4,
Kitty [74]

Answer:

D(4,-3)

Step-by-step explanation:

Given three of the vertices of the square: A(4, -7), B(8, -7),C(8, -3)

Let the coordinate of the fourth vertex be D(x,y).

We know that diagonals of a square are perpendicular bisector. So, the midpoint of both diagonals is the same.

The diagonals are BD and AC

Midpoint of BD = Midpoint of AC

\left(\dfrac{8+x}{2},\dfrac{-7+y}{2}\right) =\left(\dfrac{4+8}{2},\dfrac{-7+(-3)}{2}\right)\\ \left(\dfrac{8+x}{2},\dfrac{y-7}{2}\right) =\left(\dfrac{12}{2},\dfrac{-10}{2}\right)\\ \left(\dfrac{8+x}{2},\dfrac{y-7}{2}\right) =\left(6,-5\right)\\$Therefore$:\\\dfrac{8+x}{2}=6\\8+x=12\\x=12-8\\x=4\\$Similarly$\\\dfrac{y-7}{2}=-5\\y-7=-5*2\\y-7=-10\\y=-10+7=-3

The coordinates of the fourth vertex is D(4,-3)

The smaller number is 63 I think.

I think this because 150/2 is 75

75-12=63

the small number would be 63

If you begin at a location with the coordinates 0 degree lat. and 0 degree long., and first travelling east 1/3 of the way aroun
Hatshy [7]

We can consider east and north direction as x and y axes respectively.

latitude 0 and longitude 0 be the origin.

Let 'a' be the total way around the world

so, if I travel east 1/3 of the way around the world, x co-ordinate  = 1/3 a

if I travel north 1/3 of the way around the world, y co-ordinate  = 1/3 a

So the coordinates of your new location are(1/3 a, 1/3 a)
