Given the median qr and trapezoid mnop what is the value of x 3x-8
2 answers:
<u>Answer-</u>
The value of x was found to be 7.
<u>Solution-</u>
In the given trapezium, the parallel sides are NO, MP and QR is the median.
From the geometric properties of trapezium, we know that,
The median line is always parallel to the bases and its length is the average length of the bases.
Therefore, the value of x is 7.

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.
