value of x is 50. because diameter AB divide the circle in 180. that's why
X=180-130

COB = AOB - AOC = 180 - 130 = 50
COB and CDB are on the same segment BC
So CDB = 1/2 × COB
(Because COB is the angle at centre which is 2 times the angle formed by the same segment on the circle. There is a theorem regarding this. You can look it up in your book)
=> CDB = 1/2 × 50
=> CDB = 25°
=> x = 25°
