The sum of the interior angles of a triangle is always 180 degrees. Therefore, the remaining interior angle of the triangle can be found by subtracting the given angles from 180:
180 - 41 - 53 = 86 degrees
Since the exterior angle formed by the extended line is supplementary to the interior angle at the top vertex, angle x is also 86 degrees.
Use the image to answer the question.
An illustration shows a triangle with an interior angle at the left vertex of 41 degrees and an interior angle at the right vertex of 53 degrees. A line extending from the top vertex forms an exterior angle that is labeled x.
Find angle x .
