Question

Find the measure of the arc or angle indicated

Answer 1

Answer:

the term arc is used for a portion of a circle along its circumference. The size of the arc is usually given by the size of the angle subtended by the arc at the center or the length of the arc. The angle subtended at the center is also known as the angle measure of an arc or informally the arc measure.

Answer 2

Answer:

A) 64°

Step-by-step explanation:

By intersecting secants theorem:

$m\angle ACB = \frac{1}{2} (m\widehat {AS} - m\widehat {BD})$

$35\degree = \frac{1}{2} (134\degree - m\widehat {BD})$

$70\degree =134\degree - m\widehat {BD}$

$m\widehat {BD} =134\degree - 70\degree$

$m\widehat {BD} =64\degree$
