ABC is an isosceles triangle such that AB = AC and AD is the median to the base BC with ∠ABC = 35°. Then ∠BAD is
-
- 35°
- 55°
- 70°
- 110°
- 35°
Correct Option: B
On the basis of given in question , we draw a figure of an isosceles triangle ABC ,
Given , AB = AC and BD = DC
∴ ∠ADB = ∠ADC = 90°
∠ABC = 35°
In ∆ ABD,
∠BAD + ∠ABD = 90°
∴ ∠BAD = 90° – 35° = 55°
