Please comment if you need clearer explanations!

Answer 2

answer 4-

100 + a=180. (lp)
a=180-100=80.
a=x. (corresponding angles)
x=80.

x=100. (corresponding angles)

answer 5 -

angle dgc =70 because line ab is parallel to line de.

angle def =70 because line bc is parallel to line ef

hope it may help you
