         p=165
         1st. side =2x-65 =2[60]-65 = 120-65= [55cm.]
         2nd. side =x = [60cm.]
         3rd. side =x-10 =60-10= [50cm.]

         p=1st.side +2nd.side +3rd side
        165=2x-65 +x + x-10
        165=4x -75
        165+75=4x
           240=4x
           240/4=4x/4
             60=x
             60cm=x
