[" If "sin(120^(@)-alpha)=sin(120^(@)-beta),0^(@)

If sin(120^(0)-alpha)=sin(120^(@)-beta),0

If sin (120^(@) - alpha) = sin (120^(@) - beta) and 0 lt alpha,beta lt pi then all the values of alpha,beta are

If sin(120^0-alpha)=sin(120^0-beta),0 lt alpha,beta lt pi, then find the relation between (alpha and betadot)

If sin(120^0-alpha)=sin(120^0-beta),0

Assertion (A):cos^(2)theta+cos^(2)(60^(@)-theta)+cos^(2)(60^(@)+theta)=(3)/(2)sin alpha-sin(120^(@)-alpha)+sin(120^(@)+alpha)=0

Assertion (A):cos^(2)theta+cos^(2)(60^(@)-theta)+cos^(2)(60^(@)+theta)=(3)/(2)sin alpha-sin(120^(@)-alpha)+sin(120^(@)+alpha)=0

Prove that sin alpha + sin (120^(@) + alpha) + sin(240^(@)+ alpha)=0

If p sin alpha=q sin(120^(@)+alpha)=r sin(240^(@)+alpha) ,prove that ,pq+qr+rp=0
