Applied similarity and scale
Use the length data for a triangular display layout with an inner outline
Triangle \(WXY\) is inside triangle \(WZA\). Points W, X and Z lie in that order on one straight side; W, Y and A lie in that order on the other. Side \(WX\) corresponds to side \(WZ\), and side \(WY\) corresponds to side \(WA\)
The corresponding angles of triangles \(WXY\) and \(WZA\) are equal
The known corresponding sides are \(WY=10\ \mathrm{cm}\) and \(WA=50\ \mathrm{cm}\)
The target side \(WX\) is \(8\ \mathrm{cm}\). Its corresponding side \(WZ\) is unknown
Calculate \(WZ\) in \(\mathrm{cm}\)
