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
It is 28.8 because if you do 48% * 60 you get 28.8 =)
Third answer, or c. (b+8>or equal to 12.4)
Answer:
60
Step-by-step explanation:
If all triangles equal 180 degrees, then all you have fo do is divide 180 by the number of points a triangle has
