A and B are points on the circumference of the circle. AB is a chord.
We Know that in a circle, the diameter subtends 90° at any point on the circumference. Alternately, if a chord subtends a right angle at a point on the circle, then the chord is a diameter.
Hence, AB is the diameter.
Hence AB = 2 * radius = 2 * 5 = 10 units.
PAB is a right angle triangle: So AB² = PA² + PB² by Pythagoras theorem.
Hence, Answer = 10² = 100 units²

Then if we join A to x and B to x
The measure from A to x = 5cm
The measure from B to x = 5cm
So, the total measure from A to B = 10cm
By Pythagoras theorem in triangle APB
Ab^2 = PA^2 + PB^2
Since AB^2 = 100cm
So, PA^2 + PB^2 = 100cm
