The adjacent angles ∠1 and ∠2 have measures of

a.38, 142
b.76, 104
c.28, 152

 A. 38, 142

Step-by-step explanation:

By the Angles of Intersecting Chords Theorem, When two chords intersect inside a circle, then the measure of the angle formed is one half the sum of chord's intercepted arcs.

Thus, by the given diagram,

⇒ ∠ 1 = 38°

Now, again by the diagram,

∠1 and ∠2 are linear pairs,

⇒ ∠1 + ∠2 = 180°

⇒ 38° + ∠2 = 180°

⇒ ∠2 = 142°

Hence, Option A is correct.
