Answer 2

Step-by-step explanation:

$there \: are \: two \: methods \: to \: solve \: this \: question \: \\ \\ \\ first \: \\ angle \: abc \: + \: angle \: cbd \: = 180degree \: by \: linear \: pair \\ \\ 110 + angle \: cbd = 180degree \\ angle \: cbd = 180 - 110 \\ 70degree \\ \\ now \: in \: triangle \: bcd \: \\ \\ angle \: cbd \: + angle \: bcd + angle \: cdb = 180 \\ \\ 70 + x + 50 = 180 \\ \\ 120 + x = 180 \\ x = 180 - 120 \\ \\ x = 60degree \: \: \\ \\ \\ and \: second \: method \: \\ \\ angle \: abd = angle \: bcd + angle \: bdc \: (because \: we \: know \: that \: the \: sum \: of \: two \: int \: angle \: is \: equal \: to \: ext \: angle) \\ \\ hence \: x = 110 - 50 = 60degree$
