Sagot :

It is given that the measure of arc BC is 182 degrees

that is

[tex]b=182^0[/tex]

the measure of arc AC is 78 degrees.

That is

[tex]a=78^0[/tex]

We know that

[tex]\angle1=\frac{1}{2}(b-a)[/tex]

Hence

[tex]\begin{gathered} \angle1=\frac{1}{2}(182^0-78^0) \\ \\ \angle1=\frac{1}{2}(104) \\ \angle1=52^0 \end{gathered}[/tex]

Hence 52 degrees is the correct answer.
