It is acute isosceles triangle
In a symmetric histogram, you have the same number of points to the left and to the right of the median. An example of this is the distribution {1,2,3,4,5}. We have 3 as the median and there are two items below the median (1,2) and two items above the median (4,5).
If we place another number into this distribution, say the number 5, then we have {1,2,3,4,5,5} and we no longer have symmetry. We can fix this by adding in 1 to get {1,1,2,3,4,5,5} and now we have symmetry again. Think of it like having a weight scale. If you add a coin on one side, then you have to add the same weight to the other side to keep balance.
Given:
The figure of a pentagon.
To find:
The value of the x.
Solution:
We know that, the sum of all interior angles of a pentagon is 540 degrees. So,



Subtract both sides by 12.


Divide both sides by 33.


Therefore, the value of the x is 16.
<h3><u>Question:</u></h3>
The present ages of Ram and Rehman are in the ratio 8:9. After 5 years, the ratio of their ages will be 9:10. Find their present ages.
<h3><u>Statement:</u></h3>
The present ages of Ram and Rehman are in the ratio 8:9. After 5 years, the ratio of their ages will be 9:10.
<h3><u>Solution:</u></h3>
- Let the present age of Ram and Rehman be 8x years and 9x years respectively.
- After 5 years, their ages will be 9x years and 10 years respectively.
- Therefore, by the problem

- So, the present age of Ram = 8x years = (8×5) years = 40 years
- The present age of Rehman = 9x years = (9×5) years = 45 years
<h3><u>Answer:</u></h3>
The present ages of Ram and Rehman are 40 years and 45 years respectively.
Answer:
It is not arithmetic, so therefore there is no common difference
Step-by-step explanation:
An arithmetic sequence is a sequence where each term increases by adding/subtracting some constant k. There is no constant term in the above pattern.
