ABC is a non-right triangle. The perpendicular to (AB) passing through B and the perpendicular to (AC) passing through C intersect at D. The perpendicular to (AB) passing through A and the perpendicular to (BC) passing through C intersect at E. Show that the points A, E, C and B are on the same circle that we will determine.

Given: △abc, ab=15, bd=9 ad ⊥ bc , m∠c=30°. find: the perimeter of the triangle.
