Answer:

∠ABC = 84°

∠CAB = 54°

Step-by-step explanation:

Assume that a point on side AB, its point F

so that,  EA = FA

Then triangle AEO ≅  triangle AFO

So,

OF = OE = BF

Triangle BOF  is isosceles.

∠CEO=180−∠ABC

So that,

180 − [tex]\frac{1}{2}[/tex]∠ABC + 42 = 180

Now solve for ∠ABC.

∠ABC = 84°

∠CAB = 180 - 84 - 42 = 54°

That's the final answer.
