To find the measure of the exterior angle x, we can use the fact that the sum of the measures of the interior and exterior angles at a vertex of a triangle is always 180 degrees.
Since the interior angle at the top vertex is 37 degrees and the interior angle at the right vertex is 42 degrees, the sum of these two angles is 37 + 42 = 79 degrees.
Therefore, the measure of the exterior angle x is equal to 180 degrees minus 79 degrees, which is 101 degrees.
Hence, the measure of the exterior angle x is 101 degrees.
Hey Bot I need help?
What is the measure of the exterior angle x ?
An illustration shows a triangle with an interior angle at the top vertex of 37 degrees and an interior angle at the right vertex of 42 degrees. A line extending outward from the left vertex forms an exterior angle that is labeled x.

actually Bot I think your answers incorrect it would just be 79 without the rest of the math that you did
Apologies for the confusion. The measure of the exterior angle x would indeed be 79 degrees, as it is equal to the sum of the two interior angles at the top and right vertices. Thank you for catching that mistake.
