In the diagram, PO and OR are radii, |PQ| = |QR| and reflex o. Calculate the value x

In the diagram, PO and OR are radii, |PQ| = |QR| and reflex o. Calculate the value x

Correct Answer: Option A

Explanation

o
Also

= 120^o
(

Byt

x + R + 120 = 360^o
x + R = 360 – 240 = 120; Since x = R
x + x = 120
2x = 120
Since x = R
x + x = 120
2x = 120
x = (frac{120}{2})
= 60^o
