Which angle is adjacent to ∠AFB?
Horizontal line BE is shown with point F labeled in the middle of the line. Ray FC extends directly up from line BE, forming a 90-degree angle. Ray FD extends up and to the right, passing through the middle of angle CFE. Ray FA extends down and to the left, below line BE.
the options are
A. ∠DFC
B. ∠EFD
C. ∠EFC
D. ∠AFE
AAAaannndd the bot gets it wrong yet again!
probably EFD, though they never said that AFD forms a straight angle.
But it is certainly NOT CFE, which is a right angle.
To determine which angle is adjacent to ∠AFB, we need to identify the angle that shares a side with ∠AFB. In this case, the side that ∠AFB shares is ray FA.
As per the description, ray FA extends down and to the left, below line BE. Since ray FA is connected to point F, which is part of ∠AFB, we can conclude that ∠AFB is adjacent to angle CFE.
Therefore, the angle adjacent to ∠AFB is angle CFE.
