Question

The length of AB is 81.96 cm.
If true then enter $1$ and if false then enter $0$

Answer 1

$\angle BDE={60}^{\circ }$, $\angle EDA={45}^{\circ }$
$BC=DE=30$
Now, In $△BDE$
$\tan 60=\frac{P}{B}=\frac{BE}{DE}$
$BE=DE\sqrt{3}$
$BE=30\sqrt{3}$
Now, In $△ADE$
$\tan 45=\frac{P}{B}=\frac{AE}{DE}$
$AE=DE=30$
Thus, $AB=AE+BE$
$AB=30+30\sqrt{3}$
$AB=81.96$ cm
