Question

in the following figure AB and CD intersect at O and angle BOC = 40° then x is​

Answer 1

Answer:

20°  is the value of x

Step-by-step explanation:

given boc=40°

so y =40     {vertically opposite angles are equal}

we know,

6x+x+y=180     [linear pair axiom]

     7x+40=180

           7x=140

             x=20°

Answer 2

Answer:

20

Step-by-step explanation:

if angle boc is 40 degree it means y is also 40 degree by voa

anda by angle sum 6x +x+40 =180

7×+40=180

7×=180-40

7×=140

×=20
