[" 3.We are given "b,c" and "sin B" such that "B" is acute and "],[b

We are given b, c and sin B such that B is acute and b lt c sin B. Then,

We are given b, c and sin B such that B is acute and b lt c sin B. Then,

a sin A-b sin B=c sin(A-B)

a sin A-b sin B=c sin(A-B)

a sin A-b sin B=c sin(A-B)

If A and B are positive acute angles such that sin (A - B) =1/2 and cos (A + B) = 1/2 , then A and B are given by

If the roots of the equation c^(2)x^(2)- c(a+b)x + ab =0 are sin A, sin B where A, B and C are the angles and a, b, c are the opposite sides of a triangle, then the triangle is : (i) right angled (ii) acute angled (iii) obtuse angled (iv) sin A + cos A = (a+b)/(c )

If sin A=3/5 , sin B=12/13 and sin C=7/25 where A,B,C are acute angles, find the value of sin (A + B + C).
