Answer:
Option A). 43°
Step-by-step explanation:
As we know from tangent chord angle theorem
Tangent chord angle ∠1 = (1/2)(Intercepted arc)
It has been given in the question tangent chord angle = ∠1
Measurement of major arc = 274°
Now measurement of intercepted arc = (360 - measurement of major arc)
Intercepted arc = (360 - 274) = 86°
Therefore tangent chord angle 1 = [tex]\frac{86}{2}=43[/tex]
Option A. 43° is the correct answer.
