Question

abcd is inscribed in circle o. the paragraph explains why ∠adc is supplementary to ∠abc. which is the statement that correctly completes the paragraph? ∠adc and ∠abc are inscribed angles in circle o. the measure of ∠adc is half the measure of arc abc and the measure of _. arcs abc and cda make up the whole circle, or 360°. so, the sum of the measures of ∠adc and ∠abc must be half of 360°, or 180°. ∠abc is equal to the measure of arc cda ∠abc is equal to the measure of arc abc ∠abc is half the measure of arc cda ∠abc is half the measure of arc abc

Explanation:

Step1: Recall inscribed - angle theorem

The measure of an inscribed angle is half the measure of its intercepted arc.

Step2: Analyze given information[SSE Completed, Client Connection Error][SSE Completed, Client Connection Error][LLM SSE On Failure]

Answer:

$\angle ABC$ is half the measure of arc $CDA$
