<u>Answer-</u>
<em>The values of x and y are </em><em>13</em><em> and </em><em>24</em><em>, respectively.</em>
<u>Solution-</u>
From the attachment, l and m are parallel lines and
---------------------1
As, when a traversal line intersects two parallel lines, same-side interior angles are supplementary, or they add up to 180 degrees.
---------------------2
As, an exterior angle is equal to the sum of the opposite interior angles.
Adding equation 1 and 2, we get,
Putting the value of x in equation 1, we get
