Answer:
A or 53 squared
Step-by-step explanation:
Answer:
.
Step-by-step explanation:
To solve this problem, we need to simplify the expression
.
We know that 
Therefore:
.
We have the following remark
-81/-54= -54/-36 = -36/ -24=...= 1.5
the sequence is geometric sequence
the common ratio of the sequence is 1.5
the sum of the five terms of the sequence is
S5= a[1- (1.5)^5 / 1-1.5], a first term,
S5= -42*6.5= - 276
Since a pentagon has five identical sides, rotating it by (360 degrees/5) will result in the same image. 360/5=72 degrees
