Intersecting chords theorem outside circle

WebIntersecting Chords Angle Theorem The measure of the angle formed by two chords that intersect inside a circle is the average of the measure of the intercepted arcs. An angle is considered to be outside a circle if the vertex of the angle is outside the circle and the sides are tangents or secants. WebPT is a tangent to the circle, PS = 9 cm and SR = 7 cm.

So we already know 2 sides for this triangle and just need to solve for L and double it to get the second chord length. r^2=a^2+L^2. L^2=r^2-a^2 = 35.23^2-17^2. L= sqrt (35.23^2-17^2) L=30.85.
