Can someone help me with this geometry question?

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

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
