  1. Step-by-step explanation:

    by ,the sum of all angles of triangle

    = (x+40) + (x-20) + (1/2x-20)=180

    = x+40 + x-20 + 1/2x-20 = 180

    =(x+x+x/2) – (40+20+20) =180

    = (x+x+x/2) -80=180

    = 5x/2 = 180+80

    = 5x/2=250

    = 5x= 250*2

    = 5x = 500

    = x=500/5

    =x = 100
