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

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

----> by central angle

therefore

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

this is false ^.^ lol
