Finding Angle ABC in Triangle

In triangle ABC, line segment BH is drawn from point B perpendicular to line segment AC, meeting it at point H. Angle ABC is labeled as $$x$$. If angle A measures $$30^{\text{°}}$$ and angle C measures $$70^{\text{°}}$$, what is the measure of angle ABC in degrees?

Use the properties of triangles and the angles formed by the perpendicular line.
