is sin A and sin C same value Share with your friends Share 1 Lovina Kansal answered this Dear student SinA≠sinCBecause if consider right triangle ABC right angled at B.Then sinA=Prependicular (BC)Hypotenuse(AC)and, sinC=Prependicular(AB)Hypotenuse(AC) regards 0 View Full Answer Laksha Leap answered this yes, in one case, it's possible that sinA = sinC. But, it has one condition for sinC = sinA that A+C = 180° if A+C doesn't equal 180°, then, sinA is not equal to the sinC. For ex: sin60 = sin120 , in this case, sum of 2 angles is 180°. 0
