Explanation of Solution
Given:
The triangle is shown below as,
Formula used:
The equation is formed with three linear variables. The sum of three angles in the triangle is 180°.
Calculation:
Consider the below triangle
Forming the equations with three variables, In triangle sum of three angles is 180°, therefore
This system can be solved by using row operations as shown below,
Multiply the first equation by -1 and add it to the second equation to produce a new second equation
Now the system with new second equation is
Add second equation to third equation to get new third equation
Divide the third equation by 2; the system is
Thus from the third equation
Back substitute this value in 2nd equation to get the value of y
Back substitute
Hence the solution is
Conclusion:
The solution is
