Triangle sum (3x+1)^0+(10x-11)^0+(3x-2)^0=180
svetlana [45]

Answer:

  • x = 12
  • 3x+1 = 37°
  • 10x-11 = 109°
  • 3x-2 = 34°

Step-by-step explanation:

Perhaps you want to know the value of x or the measures of the angles?

__

Simplifying the given equation, you get ...

  (16x -12)° = 180°

  16x = 192 . . . . . . . divide by °, add 12

  x = 12

  (3x+1)° = (3·12+1)° = 37°

  (10x-11)° = (10·12-11)° = 109°

  (3x-2)° = (3·12-2)° = 34°

x is 12, and the angle measures are 37°, 109°, 34°.

Use the matrix tool to solve the system of equations. Choose the correct ordered pair.3x + 5y = 42 6x + 5y = 54
kobusy [5.1K]
Solutions  

In Matrix we use initially based on systems of linear equations.The matrix method is similar to the method of Elimination as but is a lot cleaner than the elimination method.Solving systems of equations by Matrix Method involves expressing the system of equations in form of a matrix and then reducing that matrix into what is known as Row Echelon Form.<span> 

Calculations 

</span>⇒ <span>Rewrite the linear equations above as a matrix 
</span>
\left[\begin{array}{ccc}3&5&42\\6&5&54\\\end{array}\right] 

⇒  Apply to Row₂ : Row₂ - 2 <span>Row₁ 
</span>
\left[\begin{array}{ccc}3&5&42\\0&-5&-30\\\end{array}\right] 

⇒ <span>Simplify rows
</span>
\left[\begin{array}{ccc}3&5&42\\0&1&6\\\end{array}\right] 

Note: The matrix is now in echelon form.
<span>The steps below are for back substitution.

⇒ Apply to Row₁<span> : Row</span>₁<span> - </span>5 Row₂ 

\left[\begin{array}{ccc}3&0&12\\0&1&6\\\end{array}\right] 

⇒ <span>Simplify rows
