How do you do problems #13-18?

Answer 1

the perpendicular bisectors of \(\Delta ABC\) meet at point \(G\), so \(AG=BG=CG\)
13. \(AG=CG=25\)
16.\(BG=CG=25\)
14.\(AG=BG \Rightarrow \Delta GAB\) is a isosceles triangle \(\Rightarrow BD=AD=20\)
*Similarly:
15.\( CF=AF=24\)
17. \(CE=BE=15\)
18.\(AC=AF+CF=2\times24=48\)
