Find the angle h

Parallel+Lines+ +Dificult (binary/octet-stream)

Imagine another parallel line that cuts through "h".   We then have two sets of co - interior angle when added together make up "h" Therefore 135 + x = 180 ..   x = 45 140 + y = 180 ..   y=40   h = x + y..  h = 45 +  40 ...   h = 85
