Find the measure of the missing angle.

Answer:
a+15+38=180(Being angles on straight line)
Step-by-step explanation:
a+53=180() a=180-53() a=127
Answer:
a = 127°
Step-by-step explanation:
→ Recall the how many degrees are on a straight line
180°
→ Find the sum of angles
15 + 38 + a = 53 + a
→ Make an equation equal to 180
53 + a = 180
→ Minus 53 from both sides
a = 127°
