Which equation could be solved to find y, the measure of adc?

Answer:
C
Step-by-step explanation:
We can use the formula for chords ,and tangents
< ABC = 1/2 (ADYC - AC)
61 = 1/2(y - 119)
Answer:
Option C. [tex]\frac{1}{2}[/tex] ( y-119 ) = 61
Step-by-step explanation:
In the given diagram AB and AC are tangents to circle O.
Length of arc AC = 119°
Inscribed angle between tangents AB and BC is 61°
We have to find the measure 'y' of arc ADC.
As we know the formula
m∠A = [tex]\frac{1}{2}[/tex] [m( arc ADC ) -m(arc AC)]
Now we put the values in this equation
61 = [tex]\frac{1}{2}[/tex] ( y-119 )
So Option C 61 = [tex]\frac{1}{2}[/tex] ( y-119 ) is the answer.
