39 feet because if you multiply 13 and 3 its 39
We know that
When two chords intersect each other inside a circle, the products of their segments are equal (Intersecting Chord Theorem)
so
AE*EB=DE*EF-----> EB=DE*EF/AE
AE=4 in
DE=12 in
EF=8 in
EB=?
EB=DE*EF/AE
EB=12*8/4-----> EB=24 in
Answer:
first one is 42
second one is 3/8
Step-by-step explanation:
This is really easy.

x=12
