Question

This is a math question. Please help me.

Answer 1

Statement | Reason

1) m<DEF = m<KEF = 44° | Definition of angle bisector

2) m<DEK = m<DEF + m<KEF | Parts- Whole postulate

3) m<DEK = 44° + 44° = 88° | algebra

4) DE = KE | given

5) EF = EF | reflexive property

6) ΔDEF ≅ ΔKEF | side-angle-side

7) DF = KF | corresponding parts of congruent . triangles are congruent

8) KF =
`(1)/(2)`DK = 8 | Algebra, 7

*Note don't forget to put the degree sign on degree measures
