Step by step explation :-
96 + angle BDC = 180
angle BDC = 180 - 96 = 84
In given figure DB = CD
then,
angle Y = angle DBC
In ∆DBC,
Y + angle DBC + angle BDC = 180
2(Y) + 84 = 180
2(Y) = 180 - 84
2(Y) = 96
_________
| Y = 48 |
|_______|
In ∆ABC,
Y + 90 + X = 180
48 + 90 + X = 180
X + 138 =180
X = 180 - 138
_______
| X = 42 |
|_______|
