Circle O is a unit circle. Segment AS has length 14/5 and is tangent to circle O at A. If P is the intersection of OS with circle O, find length PS.
AO = PO
PS = [sqrt(AS2 + AO2)] - PO
PS = 1.973213749
Hello Guest!
\((\overline{PS}+r)^2=2.8^2+r^2\\ \)
\(r=1\\ \overline{PS}=1.973\)

Hello, asinus! There are 2 ways to solve this: 1/ Pythagorean theorem (above)
or
2/ AS2 = PS * SN
( N is a point on a circle opposite to point P )
Let me correct myself: there are at least 2 ways to solve this...
