Answer 1

hey it's very easy
just go through the provided picture

Answer 2

aight so, in the first questions, all the lines are concurrent, so angle AOD and BOC are vertically opposite angles, so are angle BOF and angle AOE and so is angle EOC and DOF, so the equation we get being, 2y + 2y + 5y + 2y + 2y + 5y = 360
18y = 360
y= 20
in the second question,
lines l and m have a common intersecting line making angles x and y respectively on the lines. it's given that these angles are equal. hence the lines must be parallel to each other.
similarly in lines m and n, there is an intersecting line that forms equal angles at a and b so the lines m and n are parallel as well.
now since L II m and m II n, L is parallel to n as well.
