Answer:

KF=8, m<DEK=88degrees, m<DFE=90 degrees

Step-by-step explanation:

Since we already know that DK is 16 you would just have to /2 to get KF=8

m<DEK=88degrees because we already know half of the angle because EF is a bisector. so 44*2=88

m<DFE=90degrees because since EF is a bisector it split it right down the middle meaning it would be equal to 90degrees.

Hope this helps! :)
  • KF= 8
  • ∠DEK= 88°
  • ∠DFE= 90°

What is bisector?

A line that divides the line or angle into two different or equal parts.

Given: ∠DEF = 44°, DK= 16

Since EF is bisector of angle E, then

∠DEF=∠FEK

∠FEK=44

So, ∠DEK= ∠DEF+ ∠FEK

               = 44+44= 88°

EF is a bisector divide angle middle which equals to 90°.

∠DFE=90°

Now, Since EF is bisector

KF= DK/2

   =16/2

KF= 8
