If AB < BC < CA, AD = DC, and each angle of triangle ACB is a whole number of degrees, which of the following is the maximum possible value of angle DAB? (Note: Diagram is not drawn to scale)
A) 9°
B) 14°
C) 19°
D) 21°
E)51°
Breaking Down theInfo:
From AB < BC < CA, we can use the angle relationship of a triangle to find\( \angle ACB < \angle CAB < \angleB\) .
We know\( \angleACB\) has to be at least 50 degrees.
