Answer:

E=99

F=72

D=90

Step-by-step explanation:

99 and e are vertical angles, so they are congruent. So now, you have 99+99+f+d=360.

[tex]99+99+f+d=360.\\198+f+d=360[/tex]

D is a right angle, so add 90 degrees to your answer and solve from there.

[tex]198+90+f=360\\288+f=360\\f=72[/tex]

99, 99, 90, and 72 should be the answers.
