Well from what we know about triangle is that they all add up to 180 degrees!
A right triangle would have a 90 degree angle and from the given measurements we know that the other on is 24 degrees.
So we simply subtract!!
180 - 90 = 90 degrees
90 - 24 = 66 degrees
So the measure of the third angle is 66 degrees. :)
Hope this helps. c:
Let x% be the salt concentration of first solution.
Then in 8ml, amount of salt = 
Given that to this 8ml solution, 11ml solution of a 47% salt solution is mixed.
amount of salt in 11ml of 47% salt solution is
= 
So, total amount of salt in new mixture = 
But given that this new solution is a 43% salt solution.
Hence amount of salt in new mixture of (8+11)=19ml solution of 43% salt solution is 
Hence 
8x+517 = 817
8x=817-517 = 300
x= 300/8 = 37.5
Hence the salt concentration in the first solution is 37.5%
The mean of the data set is 6.8.
<h3>What is the mean?</h3>
Mean is the average value of the given set of observations. In statistics, we also come across different types of mean such as Arithmetic, Geometric and Harmonic mean.
Given
The data set is 14, 7, 2, 8, 3.
The mean of the data set is given by;

Hence, the mean of the data set is 6.8.
