The statement third "Betty wrote an indirect proof using contradiction' and statement fourth "Ken wrote direct proof using deductive evidence" are correct.
<h3>What is an angle?</h3>
When two lines or rays converge at the same point, the measurement between them is called a "Angle."
We have Ken's statements are shown in the table:
Angle AOC = Angle BOD (given)
Angle AOB + Angle BOC = Angle BOC + Angle COD (angle addition postulate)
Angle AOB = ANgle COD (subtraction property of equality)
Ken wrote direct proof using deductive evidence.
As we can in betty's proof:
Betty wrote an indirect proof using contradiction.
Thus, the statement third "Betty wrote an indirect proof using contradiction' and statement fourth "Ken wrote direct proof using deductive evidence" are correct.

Answer:
x= 68.19°
Step-by-step explanation:
you can use inverse of cos(x)
(
) =68.19°
∴ x=68.19°
When the dilation is centered on the origin, you can multiply each of the individual coordinates by the scale factor.
All the coordinates are ±5 and the scale factor is 1/5. Multiplying those gives ±1. The only selection with all coordinates being ±1 is
.. Selection A.
You can check to see if the signs agree in detail. (They do.)

If team A scored 5 more than team B, you would subtract the 5 from 155 and be left with your answer.
Answer:
-5.238
Step-by-step explanation:
<u>Step 1: First multiply</u>
1.567 + 2.345 - 1.83(5)
<em>1.567 + 2.345 - 9.15</em>
<em />
<u>Step 2: Add the first two numbers</u>
(1.567 + 2.345) - 9.15
<em>3.912 - 9.15</em>
<em />
<u>Step 3: Add the next two numbers</u>
3.912 - 9.15
<em>-5.238</em>
<em />
Answer: -5.238
