Answer 2

Answer

Here is the solution :

Step-by-step explanation:

ABC is a triangle.

AD bisects angle A

Therefore, angle BAD = 50 degree (AD bisects A)

angle DAC = 50 degree (AD bisects A)

angle ADB = 90 degree (AD perpendicular to BC)

We know,

<B + <BAD + <ADB = 180

<B + 50 + 90 = 180

<B = 180 - 140

<B = 40

Ans : <B = 40
