To find angle b, we need to use the property that the measure of an exterior angle of a triangle is equal to the sum of the measures of its two remote interior angles.
In this case, angle b is an exterior angle of triangle ABC. So, we can find angle b by adding the measures of angles A and C.
From the image, we can see that angle A measures 52 degrees and angle C measures 38 degrees.
Therefore, angle b = angle A + angle C = 52° + 38° = 90°.
So, the answer is 90 degrees.
Use the image to answer the question.
