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
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
