Answer 1

a)

${(\overline{AB})}^{2}={12}^{2}+{16}^{2}$

${(\overline{AB})}^{2}=144+256$

${(\overline{AB})}^{2}=400$

$\overline{AB}=\sqrt{400}$

$\boxed{\boxed{\overline{AB}=20}}$

b)

$\overline{DC}=20+16=36$

${\overline{AD}}^{2}={36}^{2}+{12}^{2}$

${\overline{AD}}^{2}=1296+144$

${\overline{AD}}^{2}=1440$

$\overline{AD}=\sqrt{1440}$

$\boxed{\boxed{\overline{AD}=12\sqrt{10}}}$
