1. Problem Description

We are given a circle with center O. We are given the angle POR is 5656^\circ. We are asked to find the value of xx where the angle PQR is 2x2x.

2. Solution Steps

The angle at the center of a circle subtended by an arc is twice the angle at the circumference subtended by the same arc.
In this case, angle POR is at the center, and angle PQR is at the circumference. Therefore,
POR=2×PQRPOR = 2 \times PQR
56=2×2x56^\circ = 2 \times 2x
56=4x56 = 4x
x=564x = \frac{56}{4}
x=14x = 14

3. Final Answer

The value of xx is 14.
