Question

A tangent PQ at a point P of a circle of radius 3 cm meets a line through the centre O at a point Q such that the distance between centre and point Q is 4 cm then the length of tangent is
a) 25 cm
b) 5 cm
c) 15 cm
d) 35 cm​

Answer 1

Answer: option (b)

Step-by-step explanation:

By pythagoras theorm:-

=> (Hypotenuse)2 = (Base)2 + (Height)2

=> (Hypotenuse)2 = (3)2 + (4)2

=> (Hypotenuse)2 = 9 + 16

=> (Hypotenuse)2 = 25

=> Hypotenuse = √25

Therefore, Hypotenuse = 5
