Find hypotenuse

 sin 60 = sqrt3 /2

    sin 60 = opp / hyp = 13 sqrt3/hyp

       sqrt 3 / 2  =   13 sqrt3 /hyp

        hyp =   13 sqrt3 / (sqrt3 /2)  = 26

 

then find other leg via pythag theor

     26^2 = (13 sqrt3)+ leg2

            26^2 - (13 sqrt3)^2  = leg^2

                 leg = 13                                     Now you have the lengths of all three sides ....finish.....
