They are all 60 degrees.
Theorem: An measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.An exterior angle is formed by one side of a triangle and the extension of an adjacent side of the triangle.In the triangle at the right,
True
No. The interior angle and exterior angle at the same vertex are supplementary. Each of them is (180 degrees minus the other). In rectangles (including squares), the interior and exterior angles at each vertex are both right angles.
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line

Five of the six exterior angle measures of a nonregular hexagon measure 55, 60, 69, 57, and 57. what is the measure of the unterior angle adjacent to the sixth exterior angles?
Remote interior angles are the angles that are not adjacent to a given exterior angle but are inside the triangle. For each exterior angle of a triangle, there are two remote interior angles. The sum of these remote interior angles is equal to the measure of the exterior angle. Thus, if you have a specific exterior angle, you can identify the two corresponding remote interior angles.
The sum of an adjacent interior and its exterior angle will total to 360°. If the angles were to be equal, they would both have to be 180°. An angle of 180° is a straight line. A polygon may be composed of straight lines that intersect at vertices but a straight line has no vertex. That being the case, the answer to your question is "No".
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
In a regular polygon, the measure of the exterior angle is related to the interior angle by the equation: exterior angle = 180° - interior angle. If the exterior angle is twice the measure of the interior angle, we can set up the equation: exterior angle = 2 × interior angle. Solving this gives us the equation: 180° - interior angle = 2 × interior angle, leading to 180° = 3 × interior angle, or interior angle = 60°. This corresponds to a regular hexagon, as it has interior angles of 120° and exterior angles of 60°.
