If the length of sides of a right triangle are in AP, then the sines of the acute angle are

Let the sides of the triangle be a−d,  a,  a+d Where a>d>0.By pythagorus theorem, we have              (a+d2)=(a−d)2+a2          here a+d is the hypotenuse⇒             4ad=a2    ⇒   d=a4We have,    sinθ=aa+d=  4d4d+d=45and    sin(900−θ)=35
