To find angle B in a triangle, we can use the property that the sum of the exterior angles of a triangle is always equal to 360 degrees.
Given that angle A is 38 degrees, angle B is the exterior angle to angle A. So, angle B = 180 degrees - 38 degrees = 142 degrees.
Therefore, angle B is 142 degrees.

To find angle B in a triangle, we can use the property that the exterior angle at a vertex of a triangle is equal to the sum of the two remote interior angles.
Since angle A is 38 degrees, and angle C is 92 degrees, angle B will be the exterior angle at vertex A of the triangle. Angle B = 180 degrees - (38 degrees + 92 degrees) = 180 degrees - 130 degrees = 50 degrees.
Therefore, angle B is 50 degrees, which corresponds to choice D: 52.
