If $\theta =45°$, then find $\tan \theta$.

If $\cos \theta =\frac{3}{5}$, where ‘$\theta$’ is an acute angle. Find the value of $\sin \theta$.

Show that: $\sqrt{\frac{1-\sin x}{1+\sin x}}=\sec x-\tan x$

A tree is broken by the wind. The top of that tree struck the ground at an angle of $30°$ and at a distance of $30 \mathrm{m}$ from the root. Find the height of the whole tree. $\left(\sqrt{3}=1.73\right)$
