To find the measure of the exterior angle, we can use the fact that the sum of the measures of an interior angle and its corresponding exterior angle is always 180 degrees.
The measure of an exterior angle x would be equal to the sum of the measures of the two interior angles: 37 degrees + 42 degrees = 79 degrees.
Thus, the measure of the exterior angle x is 79 degrees.
What is the measure of the exterior angle x? (The triangle has 2 angles, 37 and 42 degrees.)
