The obtuse angle of a parallelogram is 120, find the angle between the height and the bisector of this parallelogram drawn from the apex of this angle.
Since, by condition, VВ is the bisector of the angle ABC, then the angle СВK = ABC / 2 = 120/2 = 60.
Section HВ – height to the side AD, then the angle HBC = 90.
Determine the value of the angle НВK. HВK = HВС – CВK = 90 – 60 = 30.
Answer: The angle between the height and the bisector is 30.
