Solve for x and y in the given angle equations.
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
-
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 ).
-
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: $$ 3y + 10 = 9x + 1 $$
-
Rearrange the Equation
Rearrange the equation to group like terms: $$ 3y = 9x + 1 - 10 $$ Simplifying gives: $$ 3y = 9x - 9 $$
-
Express ( y ) in terms of ( x )
To isolate ( y ), divide the entire equation by 3: $$ y = 3x - 3 $$
-
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 )): $$ 5y - 24 + 82 = 180 $$
-
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 ): $$ y = \frac{122}{5} = 24.4 $$
-
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 ).

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 ).
