Answer:
(5,-6) I think
Step-by-step explanation:
Answer:
angle CBE=15 degrees
Step-by-step explanation:
angle ECD is 60 degrees and EC=CD because equilateral triangle
angle DCB is 90 degrees and CB=CD because square
angle ECD +angle DCB= angle ECB
60+90=150=angle ECB
since triangle ECB has legs EC and CB equal in length, then it is an isosceles triangle.
so angles CBB and CBE are equal
angle CBE=(180-150)/2
angle CBE=15 degrees
The area would be 9 because the perimeter of the regular quadrilateral would be 3 and if you multiply 3 by 3 you have 9.
Yes it is d for sure and glad to see you on brainly!
