<h3>
The complete exercise is attached.</h3>
For this exercise it is important to remember that, by definition, if an angle formed by two intersecting chords has its vertex on a circle, this is called an "Inscribed angle".
The following formula is used to calculate the measure of an Inscribed angle:

You can identify in the figure that:

Then you can substitute values into the formula and solve for "x":

Then, AC is:

X is 3 y is 4 hope this helps :)
The answer is 5/12 because 1/6 converts to 2/6 and 7/12-2/6 is equal to 5/12
