A geometry problem by Syed Hamza Khalid

using Phythagoreas theorem we get: $2x^2= 17^2=289\implies x=12.02$

Solution can be found here on Youtube Channel "Mind Your Decisions".

We can use the formula $x=z \sin 45^\circ$ . We have

$x=17 (\sin 45^\circ)\approx 12.020815280171307914814354155782433667842210940704$

Finally, the desired answer is $\color{#3D99F6}\large {\boxed{12.02}}$ .
