Solution:
(i) According to the given question, We know that
![\[\angle DBC\text{ }=\angle DAC\text{ }=\text{ }{{27}^{o}}\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-962ab3d34c6c111dd1aef118c795b889_l3.png "Rendered by QuickLaTeX.com")
[Angles subtended by the same chord on the circle are equal]
(ii) According to the given question, We know that
![\[\angle ACB\text{ }=\angle ADB\text{ }=\text{ }{{33}^{o}}\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-d40a9f843a7ee8ca1993b5e96a51b9bd_l3.png "Rendered by QuickLaTeX.com")
And,
![\[\angle ACD\text{ }=\angle ABD\text{ }=\text{ }{{50}^{o}}\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-b804ae3d00d13ac83b0faa0c83118a4b_l3.png "Rendered by QuickLaTeX.com")
[Angles subtended by the same chord on the circle are equal]
Hence,
![\[\angle DCB\text{ }=\angle ACD\text{ }+\angle ACB\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-1e60c6a64c80757a999f1bcf71523951_l3.png "Rendered by QuickLaTeX.com")
![\[=\text{ }{{50}^{o}}~+\text{ }{{33}^{o}}~=\text{ }{{83}^{o}}\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-d78de53b876af87d3e4d4d420ab366de_l3.png "Rendered by QuickLaTeX.com")
