Answer 1

Answer:

The answer is $x=70^\circ$

Step-by-step explanation:

Concept :

The angle subtended by an arc of a circle at its center is twice the angle it subtends anywhere on the circle's circumference:

Here angle subtended at the center is $x$

$\therefore$ Angle subtended by the arc at the centre $=2x$

$\Rightarrow 140^\circ =2x\Rightarrow x=70^\circ$
