Answer 1

#13 ONLY!

Answer 2

\[BE \cdot DE=CE \cdot AE \]

Answer 3

BE=2(EC)
DE=3.5
so we have:
\[2(EC) \cdot 3.5=EC \cdot AE \\ \text{ hmm this means we can actually find } AE \\ 2(3.5)=AE \text{ by dividing } EC \text{ on both sides } \\ AE=7'' \\ \text{ and we know } AC=12'' \\ \]
but you can find CE now

Answer 4

but if not let me know if you are still stumped
all the theorem I applied above it called the intersecting chord theorem
