1. Problem Description
We are given a circle with center P. An angle at the center P and an inscribed angle of are shown. We are asked to find the value of . The sum of angles around a point is .
2. Solution Steps
The sum of the angles around the center of a circle is .
We have two angles at the center of the circle: and the angle corresponding to the arc where the inscribed angle is. The inscribed angle is . The central angle corresponding to the same arc is twice the inscribed angle. Let this central angle be . Therefore,
.
We know that the sum of the angles around point P is .
So, .
Substituting the value of , we have .
