case A)
we know that
If l and m are parallel lines
then
[tex]35\° =35\°[/tex] ----> by corresponding angles
the expression is true
therefore
the answer part A) is True (see the attached figure)
case B)
we know that
If l and m are parallel lines
then
[tex]120\°=118\°[/tex] ----> by corresponding angles
the expression is not true
therefore
the answer part B) is False (see the attached figure)
case C)
we know that
If l and m are parallel lines
then
[tex]70\° =70\°[/tex] ----> by alternate interior angles
the expression is true
therefore
the answer part C) is True (see the attached figure)
case D)
we know that
If l and m are parallel lines
then
[tex]50\° =50\°[/tex] ----> by alternate exterior angles
the expression is true
therefore
the answer part D) is True (see the attached figure)
The answer in the attached figure
