Answer 1

50

Answer 2

130-180:D

Answer 3

=50

Answer 4

\( \color{Black}{\Rightarrow \angle GHJ = 180 - 130 = \angle HLF }\)

Answer 5

according to the alternate interior angle theorem and supplementary angle theorem.

Answer 6

if you look at it sideways, you know that the two lines in the middle are parallel

so H is 130

and J is supplementary to H, so J is 50

and since L is coresponding to angle J, it is 50 as well (:
