Answer:
B,C,D
Step-by-step explanation:
This is a paralleogram. A paralleogram has these with angles properties
A is wrong becuase Angle K and L are adjacent angles so they form a linear pair.
B is true,
Using the two adjacent angles to a side form a linear pair,
Using the two adjacent angles to a side form a linear pair,Angle L+Angle K=180
98+Angle k=180
98+Angle k=180Angle k=82
98+Angle k=180Angle k=82Angle k and L also form a linear pair so Angle L =98
Angle J=Angle L by substitution.
C is right, I explained it above
D is right, if two angles form 180 degrees, they are supplementary.
E is wrong, I explained it in A
