If one of the interior angles of a polygon is 38°, what is the exterior angle
The exterior angle can be found by subtracting the interior angle from 180°, since the two angles form a linear pair:
180° - 38° = 142°
Therefore, the exterior angle for this polygon is 142°.
To find the measure of the exterior angle of a polygon, you can use the formula:
Exterior angle = 180° - Interior angle
In this case, if the interior angle is 38°, we can calculate the exterior angle as follows:
Exterior angle = 180° - 38°
Exterior angle = 142°
Therefore, the measure of the exterior angle is 142°.
