Cos = adjacent / hypotenuse
cos 25° = 4 / AB
cos 25° • AB = 4 / AB • AB
AB cos 25° ÷ cos 25° = 4 ÷ cos 25°
AB = 4/cos 25°
AB = 4.41 (nearest hundredth)

Answer:
Option (B)
Step-by-step explanation:
Given sequence is 45, 135, 405, 1215, 3645..........
Since it's a geometric sequence,
Common ratio of each successive term to the previous term
r =
First term of the sequence 'a' = 45
Explicit formula of a geometric sequence will be,
Recursive formula of this sequence will be,
,
Therefore, Option (B) will be the answer.
