Answer 1

112°

Explanation:

By inscribed angle theorem:

`m\widehat {BCD} = 2* m\angle BAD\\</p><p>\therefore m\widehat {BCD} = 2* 129\degree \\</p><p>\therefore m\widehat {BCD} = 258\degree\\\\</p><p>\because m\widehat{CD} = m\widehat {BCD}-m\widehat{BC} \\</p><p>\therefore m\widehat{CD} = 258\degree - 146\degree \\</p><p>\huge \red {\boxed {\therefore m\widehat{CD} = 112\degree}}`
