Question

Find the measure of the AD arc in the diagram.

123°
124°
80°
None of the above

hint Hint:

by theorem If a diameter of a circle is perpendicular to a chord, then the diameter bisects the chord and its arc

The correct answer is: 80°

option 3: $80 to the power of o space i s space t h e space c o r r e c t space a n s w e r$

HERE diameter bisect the chord so arc is equal by the theorm
so $90 space minus space x to the power of o space equals space 8 x to the power of o 9 x to the power of o space equals space 90 x to the power of o space equals 90 over 9 space equals space 10 to the power of o s o space 8 x equals space 8 cross times 10 to the power of o space equals space 80 to the power of o$
