Math Problem Statement

Solve for x in the given diagram, where (7x - 65)° and 56° are alternate interior angles formed by two parallel lines intersected by a transversal.

Solution

The problem in the image involves solving for xx in a scenario where two parallel lines are intersected by a transversal. Let's break down the steps.

Information from the Image:

  • The parallel lines are IJKLIJ \parallel KL.
  • The angle labeled (7x65)(7x - 65)^\circ at point MM is given.
  • The angle labeled 5656^\circ at point NN is also provided.
  • The angles (7x65)(7x - 65)^\circ and 5656^\circ are alternate interior angles since IJKLIJ \parallel KL, and the transversal intersects these lines.

Geometry Rule:

For parallel lines cut by a transversal, alternate interior angles are congruent. Thus, we can set up the equation: 7x65=567x - 65 = 56

Solving the Equation:

  1. Add 65 to both sides: 7x=56+657x = 56 + 65 7x=1217x = 121
  2. Divide both sides by 7: x=1217x = \frac{121}{7} x=17.29x = 17.29

Thus, x17.29x \approx 17.29.
