Answer:

Step-by-step explanation:
If we drew an auxiliary line parallel to line  and line
 and line  that intersects the vertex of
 that intersects the vertex of  , we would form three angles, one of them being
, we would form three angles, one of them being 
The largest of these angles corresponds with the angle marked as  .
.
The angle on the bottom right corresponds with the angle next to the one marked as  . Therefore, its measure is
. Therefore, its measure is  .
.
Since there are  in a circle, we can now write the following equation:
 in a circle, we can now write the following equation:
