What set of reflections and rotations could carry rectangle abcd onto itself

A reflection across the Y axis and a rotation of about 180 degrees clockwise then another rotation 180 degrees counter clockwise by 180

Step-by-step explanation:

This is correct because take a very close look at it and you will see if you reflect across the Y axis it be on the opposite side of the Y axis then rotate it at a 180 degrees clockwise then a 180 degrees rotation counter clockwise it will be at the same spot it was at before.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
