Help solve for x please (ignore my incorrect math)
IgorLugansk [536]

140° + ∠5 = 180°    <em>same side interior angles    </em>⇒  ∠5 = 40°

∠2 ≅ ∠5    <em>vertical angles   ⇒ </em>∠2 = 40°

∠8 = 53°   <em>alternate interior angles</em>

∠3 ≅ ∠8   <em>vertical angles  ⇒ </em>∠3 = 53°

x + ∠2 + ∠3 = 180°  <em>triangle sum theorem</em>

x + 40° + 53° = 180°

x + 93° = 180°

x = 87°

Answer: 87°

Note: I just realized that there is an easier way to solve this:

∠9 + 53° + x = 180°   <em>triangle sum theorem</em>

140° + ∠9 = 180°  <em>supplementary angles </em>⇒  ∠9 = 40°

40° + 53° + x = 180°  

x + 93° = 180°

x = 87°

Use whichever solutions makes sense to you.
