In the isosceles trapezoid, what is the measure of ∠1?260°50°130°25°

Answer:
50°
Explanation:
In isosceles trapezoids opposite angles are supplementary. It means that they sum to 180 degrees. So, we can find the measure of ∠1 as follows:
∠1 + 130 = 180
∠1 = 180 - 130
∠1 = 50
Therefore, the answer is
50°
