Answer:

a) 115°

b) 140°

c) 75°

d) 255°

Step-by-step explanation:

a) another line parallel to AB through E will split x into two sectors.

Parallel lines intersected by a third line makes opposite internal angles of equal value. Supplemental angles add to 180°

x = (180 - 120) + (180 - 125) = 115°

b) double application of parallel lines intersected by a third line making corresponding angles identical.

c)  more of the same

d) more of the same
