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.
