A circle can be defined as a closed, two-dimensional curved shape with no corners or edges.
A triangle is a three-sided polygon with three edges, angles, and vertices.
We will be using the properties of a circle and the angle sum property of a triangle to calculate the value of x
We know that,
∠BCD = ∠BAD (Since the angles subtended by the same arc on any point of the circumference are equal)
Thus, ∠BCD = ∠BAD = 30º
Using the interior angle sum property of a triangle,
∠BCP + ∠BPC + ∠PBC = 180º
30º + 25º + x = 180º
x = 180º - (30º + 25º)
x = 125º
