Question

Find the missing angle measures. Be sure to show your work in arriving at your answers.

Answer 1

If we are referring to the interior angles:

Angle E is 60 degrees
Angle F is 40 degrees
Angle D is 80 degrees


Explanation:
Straight lines are 180 degrees. If you subtract the given angles from 180, you would get the missing angle. For angle D, you would have to subtract angles E and F from 180.

Hope this helps!
