We got the value of 
by solving the given equations 
and 
by reduction method.
<h2>
What is reduction method?</h2>
The reduction or elimination approach includes using arithmetic operations between equations to produce equivalent equations with fewer unknowns that are simpler to analyze and evaluate.
Given equations are
.........(1)
...........(2)
We need to find the value of 
Simplifying the given equation (2) and we get
................(3)
Now, substitute the equation (3) in equation (1) and we get
Substitute the value of x in equation (3), we get
Now adding the values of x and y, we get
![\therefore e=\frac{26}{7}+\frac{52}{7}\\\Rightarrow e=-{[\frac{26+52}{7}]\\\Rightarrow e={[\frac{78}{7}]](https://tex.z-dn.net/?f=%5Ctherefore%20e%3D%5Cfrac%7B26%7D%7B7%7D%2B%5Cfrac%7B52%7D%7B7%7D%5C%5C%5CRightarrow%20e%3D-%7B%5B%5Cfrac%7B26%2B52%7D%7B7%7D%5D%5C%5C%5CRightarrow%20e%3D%7B%5B%5Cfrac%7B78%7D%7B7%7D%5D)
Therefore, the value of .

We firstly calculate the angle at the bottom left of the triangle(theta)..,
; Angle theta...
tan theta = 9/11
Angle theta = tan^-1(9/11)
; Angle theta = 39.3°
Then height x...we then use the smaller triangle..,
; tan (39.3°) = x/5.5
; x = 5.5 tan(39.3°)
Hence... x = 4.5
in many ways math is closely related to science. Mathematics is a scholarly domain, and so the mathematical community works as the scientific community does-mathematicians build on each others work and behaves in ways that push the discipline forward. This progresses contributes to scientific breakthroughs
