Quadrilateral ABCD is reflected across the X axis and then we’re flex across the Y axis to form quadrilateral ABCD is the coordinates of vertex are -7,3 what are the coordinates of vertex A

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

9 x 8 divided by (5-3)=36

24 units
