3. (Angle Bisectors). From Definition 2.9, an angle bisector is a ray that divides an angle into two angles of equal measure. (a) For a protractor at A, let the polar angles of B, C, and be b, c, d. Assuming |b−c| < 180 and D is interior to ZBAC, for what value of d will AD bisect this angle? In other words, for what D is m
