Answer:
Step-by-step explanation:
3 1/7 = 3.142857
3 10/71 = 3.140845
Actual value of pi = 3.14159 to 5 decimal places.
The actual value of pi is larger than 3.140845
The actual value of pi is smaller than 3.142857.
Note the key word is between
3.1408 < pi < 3.142857
When I taught school, I tried to impress upon my students that the counting systems of the ancients was so crude that it was a miracle they could come up with any kind of estimate especially one like 3 and 10/71.
There is mention of pi in the Bible (somewhere in 2nd Kings). It gives a value of 3. You make think that is a pretty poor estimate. but if you knew how the counting system worked, you'd be impressed by how good the answer was. The history of man is one of baby steps until now when we are making giant strides in almost every field that involves numbers. Any mysteries have multiplied by just as much.
x = 37.5 (or) ![\frac{75}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B75%7D%7B2%7D)
Solution:
Given
.
Let us take BE = x and BC = 25 + x.
To determine the value of x:
If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.
![$\frac{AC}{DE}=\frac{B C}{B E}](https://tex.z-dn.net/?f=%24%5Cfrac%7BAC%7D%7BDE%7D%3D%5Cfrac%7BB%20C%7D%7BB%20E%7D)
![$\frac{50}{30} =\frac{25+x}{x}](https://tex.z-dn.net/?f=%24%5Cfrac%7B50%7D%7B30%7D%20%3D%5Cfrac%7B25%2Bx%7D%7Bx%7D)
Do cross multiplication, we get
![50x=30(25+x)](https://tex.z-dn.net/?f=50x%3D30%2825%2Bx%29)
![50x=750+30x](https://tex.z-dn.net/?f=50x%3D750%2B30x)
Subtract 30x from both sides of the equation.
![20 x=750](https://tex.z-dn.net/?f=20%20x%3D750)
Divide by 20 on both sides of the equation, we get
x = 37.5 (or) ![\frac{75}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B75%7D%7B2%7D)
Hence the value of x is 37.5 or
.
4/9 + 2/3 = 10/9 or 1 and 1/9
