Use algebra to determine if segment DE is a perpendicular bisector of segment AC given that segment AC = 75

Segment BD is the altitude of triangle ABC. The measure of angle ADB = 3x+2. Solve for x.

Given: Segment BH bisects angle ABC, the measure of angle ABH=4x+7 and the measure of angle CBH=6x-3. Find the value of angle ABC.
