  1. 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
