<span>rotated 90° about the origin
(x,y) = (-y, x)
so </span><span>(5, -2) is rotated 90° about the origin = (2, 5)
answer
</span><span>b.(2, 5)</span>
Answer:
there is no answer ( I mean this system of equations can't be solved)
Step-by-step explanation:
Because the x eliminates itself there will be no point.

Answer:
The correct corresponding part is;
≅ 
Step-by-step explanation:
The information given symbolically in the diagram are;
ΔCAB is congruent to ΔCED (ΔCAB ≅ ΔCED)
Segment
is congruent to
(
≅
)
Segment
is congruent to
(
≅
)
From which, we have;
∠A ≅ ∠E by Congruent Parts of Congruent Triangles are Congruent (CPCTC)
∠B ≅ ∠D by CPCTC
Segment
is congruent to
(
≅
) by CPCTC
Segment
bisects
Segment
bisects 
Therefore, the correct option is
≅
