1) In the diagram below, if \$AD=30\$, what is \$BC\$?

[asy] size(5cm); pair A,B,C,D; B=(0,0); A=(0,8); C=(12,0); D=(12,-2); draw(A–B–C–D–A); draw(rightanglemark(C,B,A,20)); draw(rightanglemark(D,C,B,20)); label(“\$A\$”,A,NW); label(“\$B\$”,B,SW); label(“\$C\$”,C,NE); label(“\$D\$”,D,SE); label(“\$11\$”,A–B,W); label(“\$4\$”,C–D,E); [/asy]

2) If \$ST = 2,\$ \$QS = 4,\$ and \$PT = 5,\$ find \$PQ.\$
