Answer:
<h2>
37°</h2>
Step-by-step explanation:
AB is diameter.
Angle made by diameter on circumference is always 90°
![x + 90 + 53 = 180](https://tex.z-dn.net/?f=x%20%2B%2090%20%2B%2053%20%3D%20180)
Calculate the sum
![x + 143 = 180](https://tex.z-dn.net/?f=x%20%20%2B%20143%20%3D%20180)
Move constant to R.H.S and change its sign
![x = 180 - 143](https://tex.z-dn.net/?f=x%20%3D%20180%20-%20143)
Calculate the difference
![x = 37](https://tex.z-dn.net/?f=x%20%3D%2037)
Hope this helps..
