Angle aec is inscribed in circle
d. angle abc circumscribes circle
d. which equation about the relationships in the circle is true?
a. 1/2 m angle adc = m angle aec
b. 1/2 m angle abc = m angle adc
c. 1/2 m angle adc = m angle abc
d. 1/2 m angle abc = m angle aec
In GeoGebra, m∠EAD = 120°. Both m∠ADC and m∠AEC are 90° because the tangent to a circle is perpendicular to the radius drawn from the point where the tangent touches the circl
