P is the centre of two concentric circles having radius 3 cm and 5 cm. Two tangents are drawn from point A which is outside the circle. Tangent AM touches the smaller circle at point M and tangent AN touches the bigger circle at point N. If AM = 13 cm then AN = ?
(1) √153 cm
(2) √178 cm
(3) √191cm
(4) √161 cm

AP= √169 +9 = √178
AM= √178-25 =√153
