HELP AABC~ DEF. What sequence of transformations will move AABC onto ADEF?
A. A dilation by a scale factor of 2, centered at the origin, followed by
the translation (x, y) + (x + 4, y - 2)
B. A dilation by a scale factor of 2, centered at the origin, followed by
a reflection over the y-axis
C. A dilation by a scale factor of 2, centered at the origin, followed by
a 180° clockwise rotation about the origin
D. A dilation by a scale factor of 2, centered at the origin, followed by
a 180° clockwise rotation about the origin

(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
