Question 1133682
<br>
I will assume these angles are less than 90 degrees each; otherwise there are an infinite number of values for the sum of the measures of A and B.<br>
sinA = 6/13 and secB = 13/6  -->  sinA = 6/13 and cosB = 6/13.<br>
In the first quadrant, if sinA = cosB, then A and B are complementary angles, so A+B = 90 degrees.
