Answer:
106º
Step-by-step explanation:
In an isosceles trapezoid, there are two sets of cungruent angles. Multiply 74*2=148.
All quadrilaterals have interal degrees that add up to 360º. Use 360-148=212 to find the value of remaining angles. Since the angles are congruent, divide by 2.
212/2=106.
Check by adding all angels.
74+74+106+106=360✔️
