Answer:
m(intercepted arc) = 108°
Step-by-step explanation:
As we know from tangent and chord theorem in the figure attached
∠ABC = (1/2)(m intercepted arc formed by tangent and arc)
∠ABC = [tex]\frac{1}{2}(mADB)[/tex]
[tex]54=\frac{1}{2}(mADB)[/tex]
mADB = 54×2 = 108°
So the answer is measure of the intercepted arc = 108°
