    I don't know. Have you posted the right pic? I see no A,B,C,D,a,b, thing's in your picture... You find the difference of the intercepted arcs and take half of that and that is your angle that is formed outside of that thingy there

    "Angle Formed Outside of a Circle by the Intersection of: "Two Tangents" or "Two Secants" or "a Tangent and a Secant". The formulas for all THREE of these situations are the same: Angle Formed Outside = 1/2 Difference of Intercepted Arcs "

    ok you can talk the half before subtracting but you still need to subtract

    \[\frac{1}{2}(136-28) =68-14 \\ \text{ or I would have done } \frac{1}{2}(108)\] but either way the answer comes to be 54 yep

    agreed with freckles. The answer is 54 Sometimes it helps to color code things (for me anyway) to keep the arcs correct. But it's not mandatory or anything
