An image is attached to complete the question.
Answer:
The correct option is B
They are complementary.
Explanation:
Angle A, and angle B in the attached image sum up to ninety degrees.
Two angles are said to be complementary if they add up to make ninety degrees. This characteristic makes us conclude that the two given angles, which are 59°, and 31°, have the sum: 59° + 31° = 90°, and are therefore, complementary.
The correct option is B.
If the attachment is not what completes your question, then knowing the meanings of supplementary angles, and congruent angles, is enough to help decide what option to choose.
Supplementary angles are angles that sum up to make one hundred and eighty degrees. (180°)
Congruent angles are angles that have the same shape and size.
