Question

O is the center of a circle of radius 8cm. The tangent at a point A on the circle cuts a line through O at B such that AB=15cm.Find OB. With diagram. ​

Answer 1

Answer:

OA  AB.

By Pythagoras Theorem,

OB2 = OA2 + AB2

OB2 = 82 + 152

OB2 = 64 + 225

OB2 = 289  

OB2 = 172  

OB = 17 cm.
