Answer:
△ABX ≅ △ACY, by reason that they are equal and congruent to each other.
I hope this answers your question.
If the perimeter equals 30 and the length is twice the width, then the length is equal to 20 and the width is equal to 10.
ANSWER

EXPLANATION
If the graph of y=cosx is transformed to y=a cos (x−c)+d by a vertical compression by a factor of 1/3 and a translation 2 units down,
then
a=1/3
and d=-2.
The 'c' is a phase shift since it is not given, it means it is zero.
Therefore the new equation is:
y=1/3cos(x-0)−2
This simplifies to:
y=1/3cosx−2
The correct option is C.
