Step-by-step explanation:
2,4 ,10,12,19,36.5,40
Consider
.
Given:

To find:
The length of BC.
Solution:
We have,

We know that the corresponding parts of congruent triangles are congruent (CPCTC).
(CPCTC)

The length of BC is 5 m. Therefore, the correct option is A.
Add up all of the side lengths and you get 148.4 as the perimeter.
subtract that from 150 and you're left with 1.6 m left of tape
We conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.
<h3>
How to get the sum of the first 8 terms?</h3>
In an arithmetic sequence, the difference between any two consecutive terms is a constant.
Here we know that:

There are 7 times the common difference between these two values, so if d is the common difference:

Then the sum of the first 8 terms is given by:

So we conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.
