Can someone please help me solve thisss

Step-by-step explanation:

m<1= 51

m<2= 95+51 + x = 180

          146 + x = 180

            x = 34

m<3= 95 (vertical)

m<4= 95 + 47 + x = 180

         142 + x = 180

            x = 38

m<5 = 47 (vertical)

m<7= 59 (180-121=58)

m<6= 59+47+x = 180

       106 + x = 180

        x = 74

i think it would be 42cm
