Answer:
   EB ≈ 1.563 in
Step-by-step explanation:
The diagonals of a rhombus divide the figure into four congruent right triangles. Angle DAB is bisected by EA, so angle EAB is 46°/2 = 23°. EB is the side opposite, so the relevant trig relation is ...
   Sin = Opposite/Hypotenuse
   sin(EAB) = EB/AB
   EB = (4 in)sin(23°) . . . . . . multiply by the hypotenuse
   EB ≈ 1.563 in
