Question

let o be the centre of the circle find the value of x from the figure

Answer 1

here O=30°,

Step-by-step explanation:

then in a isoceles triangles two side are equal and also their angles are equal.

so,

we know that the sum of all angles in triangle is180°.

now,

O+x+x=180°

30°+2x=180°

2x=180°-30°

x=150°/2

=75°

so x=75°
