- Find the angle h
-
- 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

- \[a = 99\,^{\circ}\]\[b = 81\,^{\circ}\]\[c = 99\,^{\circ}\]
- \[d = 99\,^{\circ}\]\[e = 81\,^{\circ}\]\[f = 99\,^{\circ}\]\[g = 81\,^{\circ}\]
