Question

if O is the center of the circle, find x in below figure:​

Answer 1

35+65 is 100

x is 180-100 which is 80

so the answer is 80 degrees

Answer 2

Let the point of intersection of these lines be 0

∠BAC = ∠BOC = 35 ( Corresponding angles)

In ∆OBC

= ∠OBC + ∠BOC + ∠OCB = 180

= 65 + 35 + x = 180

= 100 + x = 180

= x = 180 - 100

= x = 80
