What are the coordinates of each point after quadrilateral ABCD is rotated 270° about the origin? Drag numbers to complete the coordinates. Numbers may be used once, more than once, or not at all.

Ok so I just did the test and the answers are A' (-5,-1) B' (-4,-3) C' (-2,-3) D' (-1,-1)

Step-by-step explanation:

A(-1,1) B(-3,2) C(-3,4) D(-1,5)

i'm doing the test, my apologies if it is incorrect

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
