Answer:
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
Direct opposite Angel's are equal so 6 =80 degrees
Answer:
r = 4
Step-by-step explanation:
z ^ (7/10) * z^ ( 33/10)
We know that a^ b* a^c = a^(b+c)
z^ (7/10 +33/10)
z^ (40/10)
z^4
r = 4
