in the diagram below, AB and BC are tangent to O. Which equation could be solved to find y, the measure of ADC
Accepted Solution
A:
Answer:AStep-by-step explanation:∠ABC is formed by 2 tangents to the circle and is measured as∠ABC = [tex]\frac{1}{2}[/tex] (m arc ADC - m arc AC ), that is [tex]\frac{1}{2}[/tex] (y - 119) = 61 → A
