Question
Suppose two secants intersect in the exterior of a circle as shown. What is greater, $\mathrm{m} \angle 1$ or $\mathrm{m} \angle 2 ?$ Justify your answer.(DIAGRAM CAN'T COPY)
Step 1
Therefore, the measure of angle 2 is given by the formula: $$m \angle 2 = \frac{1}{2} (m \text{arc } AB - m \text{arc } CD)$$ Show more…
