If Line Segment AC Is Perpendicular To Line Segment CB And The Measurement Of Angle CBD Equals 125 Degrees, Then What's The Measurement Of Angle A?

If ABD is a line segment then it is known that angle form by a line segment is 180^o. If a line CB makes an angle CBD with AC and its measurement is 125^o then the measurement of the other angle ABC will be 55^o.
ABC is a triangle whose measurements are;
Angle ABC=55^o
Angle ACD=90^o     as lines AC and CB are perpendicular
Angle CAB= 180-55-90       sum of angles of triangle is 180
Angle A=35^o
