Question

please give the correct answer with brief explanation fast ​

Answer 1

Step-by-step explanation:

given cosA= (5/13) that means sinA= (12/13)

given sinB = (4/5) that means cosB = (3/5)

now sin(A+B) = sinAcosB+cosAsinB

sin(A+B) = (12/13)×(3/5) + (5/13)×(4/5)

sin(A+B) = (36/65) + (20/65)

sin(A+B) = (56/65)
