Answer:
[tex]AC=30\\BD=13.08\\BE=15\\AB=27\\BC=13.08[/tex]
Step-by-step explanation:
[tex]AC=AE+EC=15+15=30[/tex]
[tex]DC=27[/tex]
[tex](AC)^{2} =(AD)^{2} +(DC)^{2}[/tex]
[tex](30)^{2}=(AD)^{2} +(27)^{2}[/tex]
[tex](AD)^{2} =(30)^{2} -(27)^{2} =900-729=171[/tex]
[tex]AD=\sqrt{171} =13.08\\AD=BC[/tex]
Hope this helps.
