Question

The length of AB is 25.32 cm
If true then enter $1$ and if false then enter $0$

Answer 1

In $△AQP$,$AQ=10$, $\angle APQ={30}^{\circ }$
$\tan 30=\frac{AQ}{PA}$
$\frac{1}{\sqrt{3}}=\frac{10}{PA}$
$PA=10\sqrt{3}$
In $△PBR$
$\angle PRB={45}^{\circ },RB=8$
$\tan 45=\frac{PB}{RB}$
$PB=RB=8$
Therefore, $AB=PA+PB$
$AB=8+10\sqrt{3}$
$AB=25.32$ cm
