To find the measure of angle 1 we have to apply the circle theorem.

The correct formula to find the measure of angle 1 is One-half(a° – b°).

Given:

Find the measure of angle 1.

<h3>What is the circle theorem?</h3>

As per the circle theorem, the angle of the vertex of a circle is equal to half of the difference of the intercepted arc.

The angle at the vertex is angle 1.

The intercepted angle is the angle a and angle b.

Thus, the correct formula to find the measure of angle 1 is One-half(a° – b°).
