Question

Find the values of x and y in the figure.
​

Answer 1

Answer:

by linear pair. y=180-140=40

and by exterior angle of triangle

x=30+y

x=30+40=70degree.

Answer 2

Answer:

x=110

y =40 and

Step-by-step explanation:

140+y=180{linear pair}

y=180-140

y=40

x+40+30=180{Angle sum property}

x=180-70

x=110
