Radius = 8 cm
Distance between a centre of a circle from a point = 17cm
By using Pythagoras throem,
(H)² = (B)² + (p)²
(B)² = (H)² - (P)²
(B)² = (17)² - (8)²
(B)² = 289 - 64
(B)² = 225
B = ✓225 = 15 cm
HENCE,
THE LENGTH OF A TANGENT IS 15 cm
Distance between a centre of a circle from a point = 17cm
By using Pythagoras throem,
(H)² = (B)² + (p)²
(B)² = (H)² - (P)²
(B)² = (17)² - (8)²
(B)² = 289 - 64
(B)² = 225
B = ✓225 = 15 cm
