x^2+2x-11=0\\
x^2+2x+1-12=0\\
(x+1)^2=12\\
x+1=\sqrt{12} \vee x+1=-\sqrt{12}\\

: diameter of Circle P.<br><br><br><br> 1 = m 3 = 20°, then m =
posledela

The required value of Arc BC m = 140° Option B is correct.

Given that,
AD is the diameter of the circle,
∠1 = ∠3 = 20°
Arc BC is to be determined.


<h3>What is an arc?</h3>

Arc is the measure of angle on the circumference of circle.

Here,
∠1 = arc AB
∠3 = arc CD
Now, for circle p
Since angle 1 and angle 2 are equal to the composition of the arc,
Arc  AD = Arc AB + Arc BC + Arc CD = 180
20 + Arc BC + 20 = 180
Arc BC = 180 - 40

Arc BC = 140°

Thus, the required value of Arc BC m = 140° Option B is correct.
