Given angle DAB = 60° and angle ACB = 70°
angle ADB = angle ACB = 70° ( angles in the same segment are equal )
Now in triangle ADB
angle A + angle D + angle B = 180°
( by angle sum property )
60° + 70° + angle DBA = 180°
130° + angle DBA = 180°
angle DBA = 180° - 130° = 50°
ANGLE <DBA = 50°
angle ADB = angle ACB = 70° ( angles in the same segment are equal )
Now in triangle ADB
angle A + angle D + angle B = 180°
( by angle sum property )
60° + 70° + angle DBA = 180°
130° + angle DBA = 180°
angle DBA = 180° - 130° = 50°
ANGLE <DBA = 50°
