Question

a circle is centered on point B. Points A,C, and D lie on its circumference. if ADC measures 23 degrees what does angle ABC measure

Answer 1

Answer:

$m\angle ABC=23^o$

Step-by-step explanation:

we know that

Central angle is the angle that has its vertex in the center of the circumference and the sides are radii of it

The measure of arc ADC is 23 degrees

BA=BD=BC ----->are radii of the circle B

therefore

$m\angle ABC=arc\ ADC$ ----> by central angle

therefore

$m\angle ABC=23^o$

Answer 2

Answer:46° degrees

Step-by-step explanation: have a good day loves
