Answer:
true
Step-by-step explanation: In a concave polygon, each interior angle is less than 180°.
PART A
The geometric sequence is defined by the equation

To find the first three terms, we put n=1,2,3
When n=1,



When n=2,



When n=3



The first three terms are,

PART B
The common ratio can be found using any two consecutive terms.
The common ratio is given by,



PART C
To find

We substitute n=11 into the equation of the geometric sequence.

This implies that,


0.73+0.68+0.88+0.74+0.81=3.84
3.84 divided by 5
=0.768x100
=76.8% or 77%
Break it down to smaller shapes find their aree and then add all of the shapes ares together. I got 44 but I did it quickly don’t forget to divide by two when finding the area of a triangle.
