Calculate the area of the shaded region in the rectangle.<br> 20'<br> 5'<br> 12<br> 7
ioda

Answer:

20 x 12 = 240(total area)

20 - 7 = 13(base)

12 - 5 = 7(height)

13 x 7 = 91

91 divided by 2 (x 1/2) = 45.5

Now we subtract the area of the non shaded region from the shaded region.

240 - 45.5 = 194.5 is your answer.

Triangle ABC is reflected across the x-axis, and then across the y-axis. Which rotation is equivalent to this composition of tra
larisa [96]

Answer:

<em>C) 180 degree rotation </em>

Step-by-step explanation:

While reflecting a point, with coordinates as (x, y), over x axis the new co-ordinates become (x, -y)

⇒(x, y) → (x, -y)

While reflecting a point, with coordinates as (x, y), over y axis the new co-ordinates become (-x, y)

⇒(x, y) → (-x, y)

So, when these two operations are combined, they the rule followed is,

⇒(x, y) → (-x, -y)

We also know that while rotating a point, with coordinates as (x, y), 180° the new co-ordinates become (-x, -y)

⇒(x, y) → (-x, -y)

Therefore, reflecting a point over x axis and then over y axis will yield the same result as rotating a point 180°.
