Question

please Answer me for these question​

Answer 1

question 4

x+50+130+12=360

x=360-192

question 5

x +90= 180. (linear pair )

x=90

z+30=180 (linear equation)

z=150

x+y+z=180 ( exterior angles)

y=

x

Answer 2

Step-by-step explanation:

Q. 4

we know all angles of a quadilateral =360°

so

50+130+12+x=360

=192+x=360

x=360-192

x=168 ans.

Q. 5

30+90+x=180

120+x=180

=x=60

z=30

x=180-90=90(as a straight line makes a 180 angle)

y=180-60=120 (as a straight line makes a 180 angle)

x+y+z=30+90+120=240

Q. 6 50/10=5/1=5:1

5/0.5= 10:1
