36°
The adjacent angles 21 and 22 have measures of:
38, 142
76, 104
28, 152
Answer:
Option "A" might be the correct option
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.
In the diagram : -
⇒ ∠ 1 = 38°
Now, again by the diagram,
∠1 and ∠2 are linear pairs,
⇒ ∠1 + ∠2 = 180°
⇒ 38° + ∠2 = 180°
⇒ ∠2 = 142°
Answer:
38,142.
Step-by-step explanation:
The measure of angle 1 = the sum of the measure of the 2 arcs / 2
= (36 + 40) / 2
= 38 degrees.
