Answer:
Angle
= (bigArc - smallArc)/2
Step-by-step explanation:
Draw a circle and put a point outside the circle. Draw two lines from the point. They are secants if they both touch the circle twice. See image.
The secants cut off a Big Arc and a Small Arc. The angle is the (BigArc - SmallArc) and then ÷ 2.
see image.
