Triangle ABC is rotated 90 degrees counterclockwise about the origin. Which of the
following is true in regards to A'B'C?

A) A’B’C is a rigid transformation located in e quadrant II.

B)A’B’C’ is a non-rigid transformation located in quadrant II.

C)A’B’C’ is a non-rigid transformation located in quadrant IV.

D) A’B’C’ is a rigid transformation located in quadrant IV.

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !

(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
