The last series, 6+2+6/9+6/27+..., converges.
A series converges is r<1; in the first series r=1; in the second, r=2; in the third, r=2; and in the last, r=1/3.
Answer:
d = 90°
e = 41°
f = 139°
Step-by-step explanation:
d + 90° = 180° (Angles in linear pair)
-> d = 180° - 90°
-> d = 90°
e = 41° (vertical angles)
f + 41° = 180° (Angles in linear pair)
-> f = 180° - 41°
-> f = 139°
