Question

The measure of ∠1 = 43 86 274

Answer 1

Answer:

$m$

Step-by-step explanation:

we know that

The inscribed angle measures half that of the arc comprising

so

$m$

$m$

$m$

Answer 2

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 = $\frac{86}{2}=43$

Option A. 43° is the correct answer.
