Type the correct answer in the box. Use numerals
instead of words. If necessary, use / for the fraction bar.
Polygon ABCD, shown in the figure, is dilated by a scale factor of 8 with the
origin as the center of dilation, resulting in the image A'B'C'D'.
The slope of CD is

step-by-step explanation:

4 + 5 7/9= 9 7/9

step-by-step explanation:

(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
