Answer:
Becky completed the proof incorrectly.
Step-by-step explanation:
The only difference of the two proofs, at least what I can see, is the reason for step 2. Angie claims that it is the Definition of Supplementary Angles, while Becky claims Angle Addition Postulate.
The Definition of Supplementary Angles states that m∠A + m∠B = 180°.
While the Angle Addition Postulate states that m∠A + m∠B = m∠C.
Because the context used is that m∠AKG + m∠GKB = 180° and m∠GKB + m∠HKB = 180°, it would be using the Definition of Supplementary Angles.
So Becky is the one who is incorrect.
Answer:
B.) 18
Step-by-step explanation:
90 + 72 = 162
180 - 162 = 18
(90 comes from the right angle)
(72 is already present)
(a triangle adds up to 180 degrees)

Answer:
14,300,000
Step-by-step explanation:
Starting off with 14 million, you haven't reached the 100 thousands or below yet where you should start. The next digit, 3, is in the 100 thousands place and the digit next to it is four. When you're rounding, if the digit is greater than five, then you round up. (example: if the number you're rounding is 67, seven is greater than five so you would round it to 70.) If the digit you are rounding is smaller than 5 then you would round down. (Example: if the number you're rounding is 34, then you would round down because four is smaller than five or higher.) Since in your problem, you have 345,678, (we've already discussed the 14 million part in the beginning) 4 is smaller than 5 or higher so it would round 14,345,678 to 14,300,678. However, since we've already rounded the part we meant to do, every digit after would turn to 0. The final result would be 14,300,000.
The answer to your question is -2.5
I got my answer because R is in the middle of -3 and -2 and -2.5 is in the middle of both of the numbers.
Hope I helped :D
