Final answer:
The question lacks sufficient data to find the exact measures of the missing angles in the isosceles trapezoid, making option A) the correct choice.
Step-by-step explanation:
The student's question involves finding the missing angles in a isosceles trapezoid. Isosceles trapezoids have two pairs of angles that are equal respectively. By using properties of parallelograms and the fact that the sum of interior angles in a quadrilateral is 360 degrees, we can deduce the missing angle measures by setting up equations based on the information provided in the question or diagram. The provided data seems insufficient to determine the exact missing angles. Therefore, option A) 'Not enough information provided' is the most appropriate choice in this context.
