I WILL MARK BRAINIEST
I got one correct there should be about one more that’s also right
                                             
                                          
                                          
                                        
											 
											So essentially an adjacent angle is when two angles have a common side and a common vertex.
So knowing that we can determine from the picture all the adjacent angles:
D) <2 and <3 are adjacent angles
E) <1 and <3 are adjacent angles
F) <1 and <5 are adjacent angles
I hope this helps.
