6. (02.03 MC) Triangle ABC is shown. A is at negative 5, 4. B is at negative 7, 2. C is at negative 2, 3. If triangle ABC is rotated 180 degrees, reflected over the y-axis, and reflected over the x-axis, where will point A' lie? (5 points) (5, −4) (4, −5) (−4, 5) (−5, 4)

(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
