Given : PT is a tangent at T to a circle whose centre is O
OP=41cm,OT 9cm.
To Find : PT
Solution:
OP = 41 cm
OT = 9 cm
PT = ?
PT is tangent to circle
OT is radius
OP² = OT² + PT²
=> 41² = 9² + PT²
=> PT² = 41² - 9²
=> PT² = (41 + 9) (41 - 9)
=> PT² = (50)32)
=> PT² = 2*25 * 2 * 16
=> PT² = 2² * 5² * 4²
=> PT = 2 * 5 * 4
=> PT = 40 cm
PT = 40 cm
