If π/2 < A < π and π < B < 3π/2, sinA = 3/7 and secB = -5/2, Locate angles A and B in diagrams and then find the exact value for sin(B - A). *** In the solution my teacher gave, he made the adjacent angle of A positive while finding the exact value, which I don't understand since it seems like it should be negative according to the diagram.

Figure in plane geometry formed by two rays or lines that share a common endpoint, called the vertex. The angle is measured in degrees using a protractor. The different types of angles are acute, obtuse, right, straight, and reflex.
