What is the measure of the angle at the tail end of the kite?

Answer:
58°
Step-by-step explanation:
The sum of interior angles is equal to 360° the rectangle has two right angles (right angles has a measure of 90°) and one of the angle is given as 122° so if we add these up
122 + 90 + 90 = 302 and 360 - 302 = 58.
