CDE is reflected over the x axis . what are the vertices of c'd'e please help!! <3

Answer: Choice D (aka 4th option)
C ' (-8, 1)
D ' (-6, 5)
E ' (-2, 4)
===========================================================
Explanation:
The x axis reflection rule is
x stays the same while y flips in sign (positive to negative, or vice versa).
- A point like C(-8, -1) will reflect to C ' (-8, 1)
- The point D(-6, -5) reflects to D ' (-6, 5)
- Lastly, the point E(-2, -4) reflects to E ' (-2, 4)
All of this points to Choice D as the final answer.

Answer:
H
Step-by-step explanation:
The parallel line BC divides the sides AD and AE in proportion, that is
=
, that is
=
( cross- multiply )
3AC = 8 ( divide both sides by 3 )
AC = = 2
, hence
AE = AC + CE
= 2 + 4 = 6
→ H
Answer:
The vertices are (-16,-5) and (14,-5)
The foci are (-26,-5) and (24,-5)

Since O is circumscribed about quadrilateral DEFG, the value of x is equal to: D. 68°.
<h3>What is a supplementary angle?</h3>A supplementary angle can be defined as two (2) angles or arc whose sum is always equal to 180 degrees. Mathematically, a supplementary angle can be calculated as follows:
Q + R = 180°.
In Geometry, the opposite angles of any cyclic quadrilateral that is inscribed inside a circle always form a supplementary angle. Thus, we would determine the value of x by using the mathematical expression above:
x + 112° = 180°
x = 180° - 112°
x = 68°
