Dörtgende Kenar Uzunluğu Hesaplama

3. ABCD dörtgen

$[AB] \perp [BD]$

$[BC] \perp [CD]$

$m(\widehat{BAD}) = 45^\circ$

$m(\widehat{DBC}) = 45^\circ$

$|BC| = 3 \text{ cm}$

olduğuna göre, $|AD| = x$'in kaç santimetre olduğunu bulunuz.

Soruda görsel içerik var: A geometric diagram of a quadrilateral ABCD. The vertices are labeled A, B, C, D. There is a right angle at vertex B formed by segments AB and BD, and another right angle at vertex C formed by BC and CD. Angle BAD is $45^\circ$ and angle DBC is $45^\circ$. The length of segment BC is 3 cm. Segment AD is labeled with the variable x. The entire figure consists of two adjacent right-angled triangles sharing the side BD.
