Question

The length of the tangent to a circle from a point 17 Cm from its center 8 Cm.find the radius of the circle ​

Answer 1

Answer:

15

Step-by-step explanation:

u can find it by using pythagoras theorem

i.e,the radius will be a perpendicular and the line from centre to the external point will be hypotenuse...

and as we know a tangent always makes a 90 degree angle with the radius

therefore,hypotenuse =17cm

base=8 cm

h^2=p^2+b^2

289-64=p^2

225=p^2

15=p

where p=radius=15
