Question

If the measure of ab is 134 what is the measure of abc , the tangent-chord angle

Answer 1

The answer is 67 for apex!

Answer 2

The measure of ∠ABC is 67°.

Explanation:

Consider the provided figure:

Tangent chord angle =
`(1)/(2)` intercepted arc

Now consider the provided figure;

Substitute the value of intercepted arc = 134° in the above formula.

Tangent chord angle =
`(1)/(2)*134`

Tangent chord angle =
`67`

Hence, the measure of ∠ABC is 67°.
