To determine the measure of angle ZEFH, we need to consider the relationship between a tangent and a radius drawn to the point of tangency on a circle.
In a circle, when a radius is drawn to the point of tangency, it forms a right angle (90 degrees) with the tangent line. Therefore, angle ZEFH is a right angle, and its measure is:
90°
