Slide 3

• 
• Find the angle h

Slide 4

• 
• 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

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