In ∆ABC, ∠B = 45°, ∠C = 55° and the bisector of ∠A meets BC at point D. Then ∠ADB will be

Answer 1

Answer:

Hope my answer helps you mate :-)

Step-by-step explanation:

In Triangle ABC

By angle sum property

A+B+C=180

A+55+45=180

A=80 degree

Now in Triangle ADB

Angle BAD=40 as AD is bisector of angle A

Now in triangle BAD by angle sum property of triangle

BAD+B+ADB=180

40+45+ADB=180

ADB=180-85=95
