<u>Answer:</u>
W (-1, 4) ---> W' (-4, -1)
X (-1, 2) ---> X' (-2, -1)
Y (2, 2) ---> Y' (-2, 2)
Z (2, 4) ---> Z' (-4, 2)
<u>Step-by-step explanation:</u>
We have with a rectangular figure WXYZ and we are to find the coordinates of its vertices W'X'Y'Z' after the transformation of 90° rotation.
We know that, the rule for 90° rotation of a point (x, y) gives (-y, x).
So,
W (-1, 4) ---> W' (-4, -1)
X (-1, 2) ---> X' (-2, -1)
Y (2, 2) ---> Y' (-2, 2)
Z (2, 4) ---> Z' (-4, 2)
The answer I believe would be "D", the full shape of the triangle should add up to a total of 360 degrees, so adding "123" and "41" comes out to "164" So then you would just see which of the options would add up to 360.
8w
he recycles 8 per week which means if you wanted to know how many he had recycled after 10 weeks you would multiply 8 by 10 to find out. so its 8w
