If \sin A = \frac{12}{13}sinA= 13
12

and \cos B=\frac{11}{61}cosB=
61
11

and angles A and B are in Quadrant I, find the value of \tan(A+B)tan(A+B).

“exterior angles of triangles. an exterior (or external) angle is the angle between one side of a triangle and the extension of an adjacent side. try this drag the orange dots on any vertex to reshape the triangle.” look to get to the answer i explained what it means and other things i hope it you .
