A and B are positive acute angles. If sin A=(3/5) and cosB= (12/13) find the value of sin (A+B)

first you have to find the angles cosA and
SinB using pythogoras theorem. Then using the property expand Sin(A+B)and then substitute the given values. similarly do the same for cos(A+B) and find the quadrant in which A+B lies. That's it!!!
