Question

Value of x in the adjoining figure is- *


a)250⁰ b)260⁰ c)190⁰ d)350⁰​

Answer 1

Answer:

b) 260⁰​

Step-by-step explanation:

Here,

∠BAC  = $\frac{1}{2}$∠BOC (∵The angle subtended by an arc at the centre is double the angle subtended by it at any point on the remaining part of the circle)

Now,

∠y = 100⁰​

∠x + ∠y = 360⁰​

∠x = 360⁰​ - 100⁰​

∴ ∠x = 260⁰​
