Answer:
78.2°
Step-by-step explanation:
To find the measure of angle C, we can use the properties of parallelograms. In a parallelogram, opposite angles are congruent. This means that angle A is congruent to angle C, and angle B is congruent to angle D.
Since we know that angle A measures 78.2°, we can conclude that angle C also measures 78.2°.
Therefore, the measure of angle C is 78.2°.
