In the given figure, O is the centre of a circle, TN is a Tangent, AN = 12 cm and OE = 5 cm. Find the length of NE.
1 answer:
Answer:
NE = 8 cm
Step-by-step explanation:
Radius OA = OE = 5 cm
In right triangle OAN, OA² + AN² = ON²
5² + 12² = ON²
ON² = 25 + 144 = 169
so ON = 13 cm
NE = ON - OE = 13 - 5 = 8 cm
