 The Unknown Side (Posted on 2002-07-01)
ABC is a triangle:
• Angle A < 90.
• D is a point on BC such that BD = DC.
• M is a point on BC such that AM is perpendicular to BC.

If
• AD = 10,
• BC = 12 and
• MC = 11
find the length of AC.

MC = 11 gives BM = 1 and MD = 5

with MD = 5, AD = 10, AMD = 90
find AM

with AM = x, BM = 1, AMB = 90
find AB

with AB = x, BD = 6, AD = 10
find ABC

with
ABC = x, AB = y, BC = 12
find AC
