What is the sum of the interior angles of a triangle?

If two angles of a triangle are 24 degrees and 37 degrees, what is the measure of the third angle?

Given a straight line, if one angle is 104 degrees, what is the measure of the adjacent angle?

In a triangle, if one angle is 90 degrees and another is 43 degrees, what is the measure of the third angle?

If a 90-degree angle is bisected, what is the measure of each resulting angle?

In a triangle, if two angles are 45 degrees each, what is the measure of the third angle?

If two parallel lines are cut by a transversal, what is the relationship between alternate interior angles?

Given a triangle with angles 9x + 3, 11x - 21, and 5x - 2, what is the value of x if the sum of the angles is 180 degrees?

If an exterior angle of a triangle is 104 degrees and one of the opposite interior angles is 25 degrees, what is the measure of the other opposite interior angle?

In a triangle, if the exterior angle is 18x - 15 and the two opposite interior angles are 13x - 11 and 4x + 1, what is the value of x?
