Answer:

a=127

Step-by-step explanation:

Okay so basically thats a straight line that the angles are on right? Yes so that entire angle is equal to 180 so you set up the equation 15+38+a=180 and then you simplify which is 53+a=180, then you subtract 52 from both sides and you get a=127. Hope this helps :)
