2. What is the value of x if the angles<br> within a triangle are 2x +1, 7x-2 and 3x<br> +5?
noname [10]

Answer:

 x=14.67\\°

Step-by-step explanation:

The sum of all the three angles of any triangle is 180°

Putting sum of all the angles given equals to 180°

                      (2x+1)+(7x-2)+(3x+5)=180°

                              2x+7x+3x+1-2+5=180°

                                                         12x+4=180°

                                                                   x=\frac{180-4}{12}

                                                                   x=14.67\\°

The value of the x is found on solving the given angles of the triangles.

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

2x + y = 3

-2x + 5y = -9

<u>Step 2: Solve for </u><em><u>y</u></em>

<em>Elimination</em>

  1. Combine equations:                    6y = -6
  2. Divide 6 on both sides:               y = -1

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Define equation:                    2x + y = 3
  2. Substitute in <em>y</em>:                       2x - 1 = 3
  3. Isolate <em>y</em> term:                        2x = 4
  4. Isolate <em>y</em>:                                 x = 2
