Question

(b) Find x + y +z+w​

Answer 1

Answer:

sorry dear my maths is very bad

Answer 2

z+60=180(linear pair)

z=180-60

z=120

y+80=180(linear pair)

y=180-80

y=100

x+120=180

x=180-120

x=60

we will take linear pair of w as a :

Now ,

120+80+60+a =360 ( angle sum property )

260+a =360

a = 360-260

a = 100

w+100=180 ( linear pair )

w=180-100

w=80

So, this is your answer
