There are different kinds of angles. The statement that will accurately correct the two-column proof is that the definition of angle on a straight line.
<h3>What is straight angle? </h3>- This is an angle whose sides sit in opposite directions from the vertex usually in the same straight line and is said to be equals two right angles.
Two angles are known to be supplementary when their measures if sum up reaches 180 degrees.
Conclusively, Looking at the angle, m∠ZRY = 180°, this is because angle ZRY is a straight angle and it is not a supplementary angle.
Therefore option A is the correct answer (Image attached)

Answer:
The percentage of scores higher than 72 is 99.85%
Explanation:
The empirical rule states that about 68% of observations falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ)
We can use the relationship below
255-σ(61)=72
61σ=255-72
61σ=183
σ=3
The area is as shaded below
The percentage of scores higher than 72 is 99.7%+0.15%=99.85%
