Segment WC is tangent to circle O at point W.

CO¯¯¯¯¯¯¯¯, CW¯¯¯¯¯¯¯¯¯, and OW¯¯¯¯¯¯¯¯¯ are drawn in to create △OWC.

If WC=15 and CO=17, what is OW?

8 units.

Step-by-step explanation:

It is given that segment WC is tangent to circle O at point W.

WC=15 and CO=17.

We need to find the measure of OW.

We know that radius are perpendicular to the tangents at the point of tangency.

Using Pythagoras theorem in △OWC.

Taking square root on both sides.

Therefore, the measure of OW is 8 units.
