Solution

\[\boldsymbol{4 : \sqrt{3}}\]

Given,

\[\Rightarrow \sin \theta = 0.5\]

\[\Rightarrow \sin \theta = \frac{5}{10}\]

\[\Rightarrow \sin \theta = \frac{1}{2}\]

\[\Rightarrow \sin \theta = \sin 30^\circ\]

\[\Rightarrow \theta = 30^\circ.\]

Substituting value of \[\theta\] in \[\tan \theta + \cot \theta\], we get:

\[\Rightarrow \tan \theta + \cot \theta\]

\[\Rightarrow \tan 30^\circ + \cot 30^\circ\]

\[\Rightarrow \frac{1}{\sqrt{3}} + \sqrt{3}\]

\[\Rightarrow \frac{1 + 3}{\sqrt{3}}\]

\[\Rightarrow \frac{4}{\sqrt{3}}\]

\[\Rightarrow 4 : \sqrt{3}\]
