a quadrilateral \( A B C D \) is drawn to circumscribe a circle such that its sides \( A B, B C, C D \) and \( A D \) touch the circle at \( P, Q, R \) and \( S \) respectively. If \( A B=x \mathrm{~cm} \),
(P) \( B C=7 \mathrm{~cm}, C R=3 \mathrm{~cm} \) and \( A S=5 \mathrm{~cm} \), then \( x= \)
