Answer : Option (1)
Step-by-step explanation :
6. Since we know that,
Exterior angle = Sum of two interior opposite angles.
Ext. ∠ACD = ∠BAC + ∠ABC
Since ∆ABC is isosceles ∆, so ∠BAC = ∠ABC
130° = ∠BAC + ∠BAC
130° = 2∠BAC
65° = ∠BAC
Now, since BE || AC so,
∠ABE = ∠BAC [ Alternate angles ]
∠ABE = n = 65°
⇒So n is 65°
