Answer:
Let the coordinates of P be (x,y). It is given that x=2y
Also,
PQ=PR
⇒
(x−2)
2
+(y+5)
2
=
(x+3)
2
+(y−6)
2
⇒
(2y−2)
2
+(y+5)
2
=
(2y+3)
2
+(y−6)

lucy
⇒
5y
2........+
+2y+29
=
5y
2
+45
⇒5y
2
+2y+29=5y
2
+45
⇒2y=16
⇒y=8
Hence, the coordinates of P are (16,8).
Explanation:
The number of images formed by two adjacent plane mirrors depends on the angle between the mirror. If (in degrees) is angle between the plane mirrors then number of images are given by, n = 360 θ − 1. We verify this formula in this experiment
