Hello, dgenerationx2!

Is there any more information?

Quote:

Find $m\angle B\text{ and }m\angle C$ .
What theorem was used to find these angles?

Code:

. . . - - - - * * * . . . * * . . . A o - - - - - - - o B . . . * \ / * . . . \ / . . . * \ / * . . . * * * . . . * / \ * . . . / \ . . . * / \ * . . . D o - - - - - - - o C . . . * * . . . * * *

The best we can say is: . $\begin {array}{ccc}m\angle B &=& \frac{1}{2}\text{arc}(AD) \\ \\[-4mm] m\angle C &=& \frac{1}{2}\text{arc}(AD) \end{array} \quad\Rightarrow\quad \angle B \:=\:\angle C$

Theorem: An inscribed angle is measured by one-half its intercepted arc.

no. that's all there is

info

This is all the information they gave me to solve this lesson. there is nothing else that i am forgetting.
