Question

Find the value of x, y and z in the following figure :-​

Answer 1

Answer:

x+50+x-30=180°(linear pair)

2x=160

x=80°

z=x+50(VOA)

z=130

y=x-30(VOA)

y=50

Answer 2

(x-30)+(x+50)=180

2x+20=180

2x=180-20

2x=160

x=160/2

x=80

x+50=80+50=130°

x -30 =80-30=50°

x-30= Y ( vertically opposite angles)

50=50

Y=50°

x+50=Z

130=130

Z=130°

here your answer
