'dz' because d and z are different values.
Well 2 to the second power would be 2 * 2 which equals 4
Given:
Point (7,12) is rotated 1260° counterclockwise about the origin.
To find:
The x-coordinate of the point after this rotation.
Solution:
If a point is rotated 360 degrees then its coordinates remains unchanged.
If a point is rotated 180 counterclockwise about the origin degrees, then

We know that,


After
rotation the coordinates of points remains same, i.e., (7,12). So, after that (7,12) is rotated 180° counterclockwise about the origin.

The point (7,12) becomes (-7,-12) after rotation of 1260° counterclockwise about the origin.
Therefore, the x-coordinate of the required point is -7.
8×5×12in^2+8×5×10in^2+12×10in^2=480 in^2+400in^2+120in^2=1000in^2 if one takes all the angles
If not then the answer would be 420in^2+120in^2=540in^2
