Answer: Angle B is 63 degrees; Angle F is 59 degrees
Explanation:
For Angle B:
We know A is 27 degrees. You can see that angle C is a right angle, so add 90 to 27 to get 117 degrees. Subtract 117 from 180 to get 63 degrees.
For Angle F:
This is the same thing for angle B. We know Angle D is 31 degrees. You can see that E is a right angle, so you add 90 to 31 to get 121 degrees. Subtract it from 180 degrees to get 59 degrees.
Hope that helps!
