Answer:

100 cm^2

Step-by-step explanation:

if FA and BF are the same and the shape is a square then the right triangles

FBC and FEC have the same area. FA is 1/2 the length of the square.

if you rotate FEC to the bottom of the square the shaded are will be 1/2 of the square. 50 = 1/2 of the square... unshaded left square = 50 , and 50 = unshaded on the right

total unshaded should be 100 cm^2

You are riding the swings at a fair. What are the coordinates of your location after a rotation of 180°?

nekit [7.7K]

Answer:

(6, -3)

Step-by-step explanation:

The actual coordinates are x = -6 and y = 3

If we rotate 180 degrees and the center of rotation is at (0,0), all we need to do is invert the signal of each axis, that is, we invert the sign of the original x-coordinate and invert the signal of the original y-coordinate.

So the final x-coordinate is - (-6) = 6

And the final y-coordinate is - (3) = -3

So the coordinates will be (6, -3).
