Understand the Problem

The question involves solving for the variable x in linear equations represented visually with angles. The user is likely working on problems involving angles formed by intersecting lines, possibly using properties of supplementary or vertical angles to find the values of x and y.

Answer

The value of \( x \) is approximately \( 9.13 \).
Answer for screen readers

The value of ( x ) is approximately ( 9.13 ).

Steps to Solve

  1. Identify Relevant Angles in the Diagram

    In the diagram, look for angles that either share a vertex and are adjacent or are across from each other (vertical angles). This will help set up equations involving the variable ( x ).

  2. Set Up Equations Using Angle Properties

    For each intersection, the angles must satisfy properties like supplementary angles (sum to ( 180^\circ )) or vertical angles (are equal).

    In the problem for section J, the angles ( (3y + 10)^\circ ) and ( (9x + 1)^\circ ) are vertical angles, which means: $$ 3y + 10 = 9x + 1 $$

  3. Rearrange the Equation

    Rearrange the equation to group like terms: $$ 3y = 9x + 1 - 10 $$ Simplifying gives: $$ 3y = 9x - 9 $$

  4. Express ( y ) in terms of ( x )

    To isolate ( y ), divide the entire equation by 3: $$ y = 3x - 3 $$

  5. Set Up Another Equation Using Other Angles

    For the other set of angles in section J, the equation formed by supplementary angles (i.e., ( (5y - 24)^\circ + 82^\circ = 180^\circ )): $$ 5y - 24 + 82 = 180 $$

  6. Simplify and Solve for ( y )

    Combine the constants: $$ 5y + 58 = 180 $$ Now subtract 58 from both sides: $$ 5y = 122 $$

    Divide by 5 to find ( y ): $$ y = \frac{122}{5} = 24.4 $$

  7. Substitute ( y ) Back to Find ( x )

    Substitute ( y ) back into the equation derived for ( y ): $$ 24.4 = 3x - 3 $$ Rearranging gives: $$ 3x = 24.4 + 3 = 27.4 $$ Dividing gives: $$ x = \frac{27.4}{3} \approx 9.1333 $$

The value of ( x ) is approximately ( 9.13 ).

This solution illustrates how to solve for variables using properties of angles formed by intersecting lines, including the use of vertical and supplementary angles.

Tips

  • Not identifying all pairs of vertical and supplementary angles.
  • Forgetting to properly simplify terms when rearranging equations.
  • Confusing the concepts of vertical angles being equal and supplementary angles summing to ( 180^\circ ).
