In ∆abc, the median am (m ∈ bc ) is perpendicular to the angle bisector bk (k ∈ ac ). find ab, if bc = 12 in. show with work

Call the point where BK intersects AM point X. BX is the altitude of ∆ABM, and it is also the angle bisector of angle ∠ABM. Hence ∆ABM is isosceles, and AB ≅ MB.

M is the midpoint of BC, which is 12 inches long. Hence MB is half that length, or 6 inches.

Since AB is the same length as MB, which is 6 inches, ...

... AB is 6 inches.

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15
