the interior adjacent angle is
55+50+x=180(angle sum property)
105+x=180
x=180-105
so therefore, x =75
55+50+x=180(angle sum property)
105+x=180
x=180-105
so therefore, x =75

Dear friend,
Let Ang. CBD as 'x'
Let Ang. CBA as 'y'
According to the property, an exterior angle of a triangle is equal to the sum of its interior angles.
So,
x = 50°+55° = 105°
Then,
x + y = 180° [Supplementary Angles]
105° + y = 180°
y = 180° - 105 ° = 75°
Answer. The interior adjacent angle is 75°
Hope it helps !!!!
