Question

please find the angle x and y​

Answer 1

We know that it is a straight line means 180.
In the middle we have x and 30 and its total sum is 90.
So,
30+ x =90
x = 90-30=60

For y-

75+60+30+y = 180. ( straight angle)
165+ y = 180
y= 180-165
y=15


HOPE IT HELPS !!

Answer 2

1. x+30=90
2. x=90-30
3. x=60
4. now

75 + 60 +y=180

135+y=180

y=180-135

y=45
