Calculating the Sum of Coordinates of Point D in Parallelogram ABCD

To find the sum of coordinates of point D in parallelogram ABCD, we can use the properties of a parallelogram. Given the coordinates of points A, B, and C, we can calculate the coordinates of point D and then find the sum of its coordinates.

Given: - Point A: (0, 0) - Point B: (5, 0) - Point C: (12, -3)

Calculating the Coordinates of Point D

The opposite sides of a parallelogram are equal in length and parallel. Therefore, we can calculate the coordinates of point D using the following formula: D = A + C - B

Let's calculate the coordinates of point D using the given coordinates of points A, B, and C.

Calculation:

Dx = Ax + Cx - Bx Dy = Ay + Cy - By

Substituting the given coordinates: Dx = 0 + 12 - 5 Dy = 0 + (-3) - 0

Result:

Dx = 12 - 5 = 7 Dy = -3

So, the coordinates of point D are (7, -3).

Sum of Coordinates of Point D

Now, let's calculate the sum of the coordinates of point D.

Sum of coordinates of point D = Dx + Dy Sum of coordinates of point D = 7 + (-3) = 4

Therefore, the sum of the coordinates of point D in parallelogram ABCD is 4.
