Question

In parallelogram ABCD show below, EB bisects < ABC.
A
If m

Answer 1

....The parallelogram is a quadrilateral, so it has 4 angles whose sum is equal to 360°.

Its opposite angles (face to face) have the same measure.

∠DAB=∠BCD=87° each

∠ADC=∠DCB = (360-87*2)/2 =93° each

The bisector is the half-line that divides an angle into two equal angles

∠ABE=∠EBC=∠ABC/2

∠EBA=∠EBC=93/2=46.5° each

→∠EBA=46.5°
