<DCX = 139°

TO FIND - x

PREREUISITE KNOWLEDGE.

CYCLIC QUADRILATERAL - A quadrilaterals is said to be cyclic if all its vertices lie on the circle

The sum of opposite angles of a cyclic quadrilaterals is 180°

ANSWER OF THE QUESTION

Now,

<DCX + <DCB = 180. ( Linear Pair)

139° + <DCB = 180

<DCB = 180 - 139 = 41°

Now,

<DCB + <BAD = 180°

41 + 3x - 2 = 180

39 + 3x = 180

3x = 180 - 39

3x = 141

x = 141/3

x = 47°
