The sum of the interior angles of a triangle is always 180 degrees.
Since we know one angle is 90 degrees and the exterior angle at the right vertex is 152 degrees, we can find angle x by subtracting these two angles from 180 degrees.
180 - 90 - 152 = -62
Since angles cannot be negative, we can conclude that angle x is 62 degrees.
Therefore, the correct answer is:
62°
62 degrees
Use the image to answer the question.
An illustration shows a triangle with a 90 degree angle at the top vertex. The interior angle of the left vertex is labeled x. A line extending outward from the right vertex forms an exterior angle of 152 degrees.
