Given:
In △ABC is a right angle triangle.
AC is 6 units longer than side BC.
To find:
The length of AC.
Solution:
Let the length of BC be x.
So, Length of AC = x+6
According to the Pythagoras theorem, in a right angle triangle
△ABC is a right angle triangle and AC is hypotenuse, so
Subtract 68 from both sides.
Divide both sides by 2.
Splitting the middle term, we get
Side cannot be negative, so x=2 only.
Now,
Therefore, the length of AC is 8 units.
The poll has an error of 600 votes. The total number of votes including the error shown by the poll is 15600 or 14400.
Statement B is correct.
<h3>What is the percentage?</h3>A percentage can be defined as a relative number that shows the hundredth part of the given number. The percentage is represented by the sign "%".
Given that In the next election, 15,000 people will actually vote for Candidate A. A poll has a percent error of 4%.
The error can be calculated as given below.
The poll has an error of 600 votes. This will affect the total number of votes in the election.
The total number of votes V including errors are given as,

or
Hence we can conclude that the total number of votes including the error shown by the poll is 15600 or 14400. Statement B is correct.
