In the figure above, segments
represent two positions of the same ladder leaning against the side
of a wall. The length of
is how much greater than the length of
(1) The length of
is 10 meters.
(2) The length of
is 5 meters.
选项
A、Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B、Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C、BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D、EACH statement ALONE is sufficient.
E、Statements (1) and (2) TOGETHER are NOT sufficient.
答案
D
解析
Note that TV= RS because they both represent the length of the same ladder. Determine TV- RV.
(1) It is given that TU= 10. Since △TVU is a 45°-45°-90° triangle, it follows that TV=
. Since RS=TU= 10 and ARVS is a 30o-60°-90° triangle, it follows that RV= 5. Therefore, TV- RV can be determined; SUFFICIENT.
(2) It is given that RV= 5. Then RS = 10 since △RVS is a 30°-60°-90° triangle. Since
RS = TU, it follows that TU= 10. This I the same information as in (1); SUFFICIENT.
The correct answer is D;
each statement alone is sufficient.
