Question

In the given figure ABCD find the value of x

a) 140
b) 160
c) 170
d) 180​

Answer 1

Answer:

a.140

Step-by-step explanation:

angle c=180-70=110(linear pair)

angle B= 180- 80=100( " )

angle A= 180-70 = 110( " )

angle D=360-110+100+110=360-320=40

x=180-angleD(linear pair)

=180-40

=140
