The smaller angle of the isosceles trapezoid is 12 °. Find the sum of the two largest angles of this trapezoid.

In an isosceles trapezoid, the upper two corners are equal and the lower two corners are equal. The sum of the top and bottom angles is 180 °. If the smaller angle is 12 °, then the larger angle is:

180 ° – 12 ° = 168 °;

Then the sum of the largest angles:

168 ° + 168 ° = 336 °.

Answer: 336 °.
