Angle Adjustment

Given the following unadjusted $4$ angles from a traverse, calculate the adjustment per angle to balance the angles. $1$st average angle: $85$ degrees $12$ minutes $10$ seconds, $2$nd average angle: $97$ degrees $25$ minutes $48$ seconds, $3$ rd average angle: $48$ degrees $17$ minutes $57$ seconds and $4$th average angle $128$ degrees $10$ minutes $45$ seconds

If the initial angle of a traverse at Point C is $56$ degrees $47$ minutes and $42$ seconds, and the necessary adjustment to the angle is $7$ seconds, what is the adjusted angle at Point C $?$ Provide your answer in decimal degrees.

You have $5$ sides in a traverse. What should the total angular closure be for the traverse.
