Answer:
c) x+20+2x+x=180
4x+20=180
4x=180-20
4x=160
x=40
e) 3x+4x+x+2x =180
10x=180
x=18
f) 92+y =180
y=180-92
y=88
y=z (Vertically opposite angle)
so, z=88
x=92(Vertically opposite angle (V.O.A))
g) x=y (V.O.A)
3x=z (V.O.A)
3x+x=180
4x=180
x=45
3x =3*45=135
z=135
y=45
i) 2x+30+2x-30+2x =360
6x +0=360
6x=360
x=60
j) 5x+x+80+4x+50=360
10x+130=360
10x=360-130
10x=230
x=23
