Question

find the value of x and y in the following picture



PS: (DONT MIND THE DIGITS WRITTEN IN INK)​

Answer 1

1) x=y

so,

2x +70 =180

2x=110

x=110/2=55

2) x=

3) x=120

y=30

4) don't know

5) x=60

y=150

6) x=50

y=130

Answer 2

i. x+x+70 = 180

2x+70=180

2x=110

x = 55 degree

ii. 50+50+k=180

k=180-100=80

x=180-80

=100 degree

iii. y=30 degree (vertically opposite

angles)

30+30+x=180

x=180-60

=120 degree

iv. k+110=180(linear pair)

k=70

x = k = 70 degree

v. y+30=180(linear pair)

y=150 degree

30+90+x=180

x=180-120

=60 degree

vi. x+x+80 = 180

2x+80=180

2x=100

x = 50 degree

k+y=180(linear pair)

50+y =180

y = 130 degree
