" 8.If "sin A=(3)/(5),sin B=(5)/(13)," find "sin(A+B)?

In a Delta ABC,A is an obtuse angle.If sin A=(3)/(5),sin B=(5)/(13) then sin C=

If cos A =(5)/(13) , and sin B=(4)/(5) , find sin (A+B), where A,B,(A+B) are positive acute angles.

In a Delta ABC, A is obtuse. If sin A=(3)/(5) and sin B=(5)/(13) , then show that sin C= (16)/(65)

If B,A+B are acute angles sin(A+B)=(12)/(13),sin B=(5)/(13) then sin A=

If s in A=(3)/(5),cos B=-(12)/(13), where A and B both lie in second quadrant,find the value of sin(A+B).

If 0 lt A, B lt 90^(@), cos A= (5)/(13) and sin B =(4)/(5) then find sin (A+B) .

If sinA=3//5,cosB=5//13 & A,B are acute, find sin(A+B)

If sinA=3//5,cosB=5//13 & A,B are acute, find sin(A+B)

If sin A=(1)/(sqrt(5)) and sin B=(1)/(sqrt(10)) ,find the values of cos A and cos B .Hence using the formula cos(A+B)=cos A cos B-sin A sin B, show that (A+B)=45^(@).

In Delta ABC, A is an obtuse angle , sin A =3//5 , sin B= 5//13 " then " sin C=
