well first off ty is not a side of angle 5 but the answer to number 4 is angle 4 and angle 1
only 2 sides make an angle so there couldnt be 3 answers and ty isnt a part of angle 5, its a part of angle 4.
vertical angles are tricky because the angles have to be even, its clear that 5 and 1 arent because theyre adjacent and 2 and 5 are clearly not even also 1 and 3 arent across(vertical) from each other
