13. 7=108 degrees
14. 8=70 degrees
15. 8=38 degrees
16. 6=73 degrees
17. 6=80 degrees
Step-by-step explanation:
13. If 6=72 what is 7
Angles on a straight line add to 180
180-72=108 degrees
14. If 9 = 110 what of 8
Angles on a straight line add to 180
180-110=70 degrees
15. If 7 =142 what of 8
Angles on a straight line add to 180
180-142=38 degrees
16. If 9 =107 what of 6
Angles on a straight line add to 180
180-107=73 degrees
17. If 8=80 what of 6
