If A and B are acute angle such that cosA =cosB then show that angle A

1.	If A and B are acute angle such that cosA =cosB then show that angle A= angleB
Answer» Cos A = Cos B - - Given AC ÷AB = BC ÷ AB - - AC = BCAngle B = Angle A - - ( since in a triangle angle opposite to equal sides are also equal ) Hence Proved Check in ncert ex. 8.1
