Answer:
B and C describe vertical angles
Step-by-step explanation:
Point R will be the common vertex of any possible pair of vertical angles.
For a given line segment, such as AE, one end will designate a side of one of the vertical angles, and the other end will designate a side of the other angle of the pair.
For example, Choice B uses the crossing segments TN and FL and identifies the vertical angles TRF and NRL.
Choice C uses segments FL and AE to identify the vertical angles LRE and FRA.
__
Choice A does not involve crossing segments. Choice D makes use of segment AE, but the other points S and N are not on the same segment.
Answer:
Circle man ez
Step-by-step explanation:
Answer:
- Leroy Sands & Walt Smith - green
- Frank Cook & Phil Hawley - yellow
- Paul O'Brien & Alan Wilson - blue
- Henry Gladstone & Don Hughes - red
Step-by-step explanation:
First of all, it is convenient to choose the false statement.
We note that statements 7 (Alan is first) and 10 (Alan did not finish) are contradictory, so one of them must be false. Statement 5 has Henry & Hughes together, so is not consistent with statement 7 (Alan & Hughes). So, statement 7 is inconsistent with two other statements, thus must be the false one.
__
The attached table shows how we parsed the statements. An "O" signifies a combination that must occur; and "X" signifies one that cannot occur. We have used "-" to fill the spaces that are inconsistent with the locations of "O". The red letters are deduced from the others.
The first complete set we found was Henry & Hughes (Don & Gladstone) who were in the (red) capsized raft and did not finish. The second complete set we found was Phil & Cook (Frank & Hawley) who were in the (yellow) raft that finished second. We know Paul & Wilson (Alan & Partner) finished last, so Phil & Cook could not have been Paul and Wilson. Finally, O'Brien and Leroy were not on the same boat, so Paul must be Paul O'Brien and Leroy must be Leroy Sands.
