Question

m∠klm = m∠lkn because they are alternate interior angles. m∠lmk = m∠mko because they are alternate interior angles. m∠lkn + x° + m∠mko = 180° because the three angles form a straight line. so the value of x must be 68 after moving the vertices, the new value of x is 141 °

Explanation:

Step1: Recall straight angle sum

The angles on a straight line sum to $180^\circ$.

Step2: Substitute known angles

We know $m\angle LKN = 85^\circ$ and $m\angle MKO = 54^\circ$. Substitute into $m\angle LKN + x^\circ + m\angle MKO = 180^\circ$:
$85 + x + 54 = 180$

Step3: Simplify and solve for $x$

Combine constants: $139 + x = 180$
Solve for $x$: $x = 180 - 139$

Step1: Use straight angle property

Angles on a straight line sum to $180^\circ$.

Step2: Substitute new implied angles

If $x=141$, let the other two angles sum to $180 - 141 = 39^\circ$, which would be the combined measure of the alternate interior angles corresponding to $\angle KLM$ and $\angle LMK$.

Answer:

$x = 41$

For the updated scenario where the new value is stated as 141:
