GEOMETRY CIRCLES PLEASE
posted by BARBIE LEE .
The diagram shows tangent circles and lines. if AB=15 CM find AC, AD and AE .
Help me reiny and other tutors please<3 thank you

just remove the open and close parentheses thank you
GEOMETRY CIRCLES PLEASE -
This is just too easy.
Remember that both tangents to the same circle from an exterior point are equal.
so AB = AC
but AC is also tangent to the small circle
so AC = AD
but AD is also a tangent to the circle at the right
so AD = AE
Since the are all equal , and AB = 15
each one of them is 15
