In a triangle ABC, if `2b=a+c` and `A-C=90`, then `sin B` equals

In !ABC , if 2b = a + c and A - C = 90^(@) , then sin B equals

In DeltaABC, if 2b =a+ c and A-C=90^(@), then sin B equal All symbols used have usual meaning in Delta ABC.]

If in a triangle ABC, b sin B = c sin C, then the triangle is-

In a triangle ABC, if cos A cos B+sin A sin B sin C=1, then a:b:c is equal to

In a triangle ABC, if a, b, c are in A.P. and (b)/(c) sin 2C + (c)/(b) sin 2B + (b)/(a) sin 2A + (a)/(b) sin 2B = 2 , then find the value of sin B

In a triangle ABC, if a, b, c are in A.P. and (b)/(c) sin 2C + (c)/(b) sin 2B + (b)/(a) sin 2A + (a)/(b) sin 2B = 2 , then find the value of sin B

In a triangle ABC, if a, b, c are in A.P. and (b)/(c) sin 2C + (c)/(b) sin 2B + (b)/(a) sin 2A + (a)/(b) sin 2B = 2 , then find the value of sin B

In a triangle ABC , if cos A cos B + sin A sin B sin C = 1 , then a:b:c is equal to
