What is the measure of

Given:

The measure of is 162°

We need to determine the measure of ∠EAB

Measure of ∠EAB:

Let us determine the measure of ∠EAB

We know that, "If a tangent and chord intersect at a point on a circle, then the measure of each angle formed is half the measure of its intercepted arc".

Applying the above theorem, we get;

Substituting , we get;

Dividing, we get;

Thus, the measure of ∠EAB is 81°

correct answer:

b.(19,-2)
