If $\theta$ is very small, then find $H$

 

In the figure, $\angle B=90°, \angle C=44°$ .

Which among the following is $\tan 44°$

For acute angle $\theta$, $b\sin \theta =a\cos \theta$

$\therefore \frac{a\sin \theta -b\cos \theta }{a\sin \theta +b\cos \theta }=$_____

In $△ABC$, A semi-circle with $DE$ as diameter is drawn such that $BC=26 \mathrm{m}$, the radius $R$ (in meter) $=$

The rod $AC$ of a TV disc antenna is fixed at right angles to the wall $AB$ and a rod $CD$ is supporting the disc as shown in the figure. If $AC=1.5 \mathrm{m}$ long and $CD=3 \mathrm{m}$, find $\tan \theta$.
