Question

Given: BOAT is an isosceles trapezoid. If T = 130°, find O.

Answer 1

180 - 130 = 50°
opposite sides add up to 180

Answer 2

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 °
