the length of the tangent to a circle from a point 17cm from its center is 8cm.Find the radius of the circle????
ANSWER => The radius of the circle is 15
STEP-BY-STEP-EXPLANATION
u can find it by using pythagoras theorem
,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
=17cmbase=8 cmh^2=p^2+b^2289-64=p^2225=p^215=pwhere p=radius=15
