Answer:

x = 60

Step-by-step explanation:

In order to make L parallel (||) to M, you want to prove that the angles are same-side interior angles since the Same-Side Interior Angle Theorem only works for parallel lines cut by a transversal.

In order to make the angles (marked with the expressions) same-side interior angles, they have to add up to 180 degrees because they are supplementary angles.

Make an equation where the two angles add up to (equal) 180.

  • (x - 5) + (2x + 5) = 180

Combine like terms on the left side of the equation.

  • 3x = 180

Divide both sides of the equation by 3.

  • x = 60

60 is the value of x that will make L || M.
