Answer
5/22 (fun fact that is my birthday)
Step-by-step explanation:
9/11 * 5/18=45/198=5/22
When considering similar triangles, we need congruent angles and proportional sides.
Hence
"Angles B and B' are congruent, and angles C and C' are congruent." is sufficient to prove similarity of two triangles.
"Segments AC and A'C' are congruent, and segments BC and B'C' are congruent." does not prove anything because we know nothing about the angles.
"Angle C=C', angle B=B', and segments BC and B'C' are congruent." would prove ABC is congruent to A'B'C' if and only if AB is congruent to A'B' (not just proportional).
"<span>Segment BC=B'C', segment AC=A'C', and angles B and B' are congruent</span>" is not sufficient to prove similarity nor congruence because SSA is not generally sufficient.
To conclude, the first option is sufficient to prove similarity (AAA)
Answer:
Option D.
Step-by-step explanation:
Consider the below figure attached with this question.
If a line passes through two points
and
, then the equation of line is

From the below figure it is clear that the a solid line passes through the points (-2,0) and (0,4). So, the equation of related line is




All area above the solid line is shaded. It means the sign of inequality is ≥.

From the below figure it is clear that the a dashed line passes through the points (2,0) and (0,2). So, the equation of related line is




All area below the dashed line is shaded. It means the sign of inequality is <.

System of inequality is


Therefore, the correct option is D.
