Question

A circle is centered on point B. Points A, C and D lie on its circumference.
IF ZABC measures 122, what does ZADC measure?

Answer 1

Answer:

  61°

Step-by-step explanation:

The inscribed angle has half the measure of the central angle subtending the same arc (AC).

  ∠ADC = (∠ABC)/2 = 122°/2

  ∠ADC = 61°
