Respuesta :
Answer;
O = 50°
Explanation and solution;
- An isosceles trapezoid is a quadrilateral that has a pair of sides that opposite and are parallel and another pair of sides that are opposite and are congruent.
- Both pairs of opposite angles in an isosceles trapezoid are supplementary which means their sum add up to 180°.
Therefore;
∠ B + ∠ A = 180° and ∠T + ∠O = 180°
Hence; ∠O = 180 -∠T
= 180 - 130°
= 50 °
