Since, each row has one more log than the row above it
so, this is arithematic sequence
We are given that
First row is
so,
Last row is
so,
Each row has one more log than the row above it
so,
now, we can find number of rows
we can plug values
we can solve for n
now, we can find total number of logs
now, we can plug values
So,
Number of logs in the pile are 119........Answer
The log in the pile is an illustration of arithmetic progression.
The number of logs in the pile is 119.
The first term of the progression is:
The last term is:
The common difference is:
First, we calculate the number of terms using:
So, we have:
Subtract 14 from both sides
Add 1 to both sides
The number of logs in the pile is calculated using the sum of n terms of an AP formula:
So, we have:
Hence, the number of logs in the pile is 119.

Answer:
When you will draw two parallel lines , and a Transversal cutting it
The Transversal may cut the parallel lines in two ways
(a)The Transversal may be perpendicular to two lines
(b) The Transversal may cut the two parallel lines which are not perpendicular.
In both the cases , 8 angles will be formed and sum of all the angles will be 720°.
When you will consider case a , there will be exactly 8 right angles.
When you will consider case b, there will be no angle equal to 90°, but sum of total angle is 720°, which will be equal to 8 right angles.
