When two lines intersect outside a circle to form angle D, the general formula for the measure of angle D is

angle D = 1/2 (mx-my). where x and y are intercepted arcs. This formula can be used when two secants form angle D. Describe

two other situations to which this formula can apply.

The three situations that the formula can be applied to include two secants intersecting the circle, a secant and a tangent intersecting the circle, and two tangents intersecting the circle. All three types of situations contain two lines intersecting to form an angle, as well as two intercepted arcs.
